# HTTP API

A complete reference for RAGFlow's RESTful API, including migration notes for RAGFlow 1.0. Before proceeding, please ensure you [have your RAGFlow API key ready for authentication](https://ragflow.io/docs/dev/acquire_ragflow_api_key).

In the standard response envelope, `message` is always a non-empty string. Successful responses default to `"success"`; error responses contain a description of the error.

---

## ERROR CODES

RAGFlow responses may contain both an HTTP status code and a business code in the JSON response body. These codes should be checked separately.

### HTTP status codes

| Code | Meaning |
|------|---------|
| 200 | The HTTP request was processed successfully. Check the response body `code` for the business result. |
| 400 | Bad request |
| 401 | Unauthorized |
| 403 | Forbidden |
| 404 | Not found |
| 409 | Conflict |
| 500 | Internal server error |

### Response body codes

| Code | Meaning |
|------|---------|
| 0 | Success |
| 10 | Not effective |
| 100 | Exception error |
| 101 | Invalid request argument |
| 102 | Invalid or missing data |
| 103 | Operation error |
| 105 | Connection error |
| 106 | Operation still running |
| 108 | Permission error |
| 109 | Authentication error |
| 400 | Bad request |
| 401 | Unauthorized |
| 403 | Forbidden |
| 404 | Not found |
| 409 | Conflict |
| 500 | Server error |
---

## Migrate to 1.0

RAGFlow 1.0 updates the public REST API. Use the canonical endpoints documented below.

The following changes require client updates:

| Area | RAGFlow 1.0 change | Client action |
|------|------------------------|---------------|
| Dataset parser selection | Dataset create and update use `parse_type` with `parser_id` (BuiltIn) or `pipeline_id` (Pipeline); responses use the canonical value `general` instead of the legacy `chunk_method: "naive"`. | Replace `chunk_method` with `"parse_type": 1` and `"parser_id": "<builtin parser>"`. For the general parser, send `"parser_id": "general"`. |
| Dataset parser configuration | RAGFlow stores and returns component-scoped parser settings. Most legacy top-level `parser_config` fields are not mapped into that component structure. | Read the returned component map and send component-scoped keys when changing parser settings. |
| Errors and authentication | Some validation business codes, messages, and authentication HTTP statuses differ from earlier releases. | Branch on documented codes rather than exact message text. |

### Removed API aliases

The following endpoint aliases are not available in RAGFlow 1.0. Use their replacements below.

### Create chat completion

**POST** `/api/v1/openai/{chat_id}/chat/completions`

Creates a model response for a given chat conversation.

:::caution REMOVED ALIAS
`POST /api/v1/chats_openai/{chat_id}/chat/completions` is not available in 1.0. Use this endpoint instead.
:::

This API follows the same request and response format as OpenAI's API. It allows you to interact with the model in a manner similar to how you would with [OpenAI's API](https://platform.openai.com/docs/api-reference/chat/create).

#### Request

- Method: POST
- URL: `/api/v1/openai/{chat_id}/chat/completions`
- Headers:
  - `'Content-Type: application/json'`
  - `'Authorization: Bearer <YOUR_API_KEY>'`
- Body:
  - `"model"`: `string` (optional)
  - `"messages"`: `object list`
  - `"stream"`: `boolean`
  - `"extra_body"`: `object` (optional)

##### Request example

```bash
curl --request POST \
     --url http://{address}/api/v1/openai/{chat_id}/chat/completions \
     --header 'Content-Type: application/json' \

        "stream": true,
        "extra_body": {
          "reference": true,
          "reference_metadata": {
            "include": true,
            "fields": ["author", "year", "source"]
          },
          "metadata_condition": {
            "logic": "and",
            "conditions": [
              {
                "name": "author",
                "comparison_operator": "is",
                "value": "bob"
              }
            ]
          }
        }
      }'
```

##### Request parameters

- `chat_id` (*Path parameter*) `string`, *Required*
  Existing chat assistant ID. The request will use that chat assistant's knowledge and settings.

- `model` (*Body parameter*) `string`
  The model used to generate the response. When `chat_id` is provided, you may also use the legacy placeholder value `"model"` to keep using the chat assistant's configured model.

- `messages` (*Body parameter*) `list[object]`, *Required*
  A list of historical chat messages used to generate the response. This must contain at least one message with the `user` role.

- `stream` (*Body parameter*) `boolean`
  Whether to receive the response as a stream. Set this to `false` explicitly if you prefer to receive the entire response in one go instead of as a stream.

- `extra_body` (*Body parameter*) `object`
  Extra request parameters:
  - `reference`: `boolean` - include reference in the final chunk (stream) or in the final message (non-stream).
  - `reference_metadata`: `object` - include document metadata in each reference chunk.
    - `include`: `boolean` - enable document metadata in reference chunks.
    - `fields`: `list[string]` - optional allowlist of metadata keys. Omit to include all. Use an empty list to include none.
  - `metadata_condition`: `object` - metadata filter conditions applied to retrieval results.

     --header 'Authorization: Bearer <YOUR_API_KEY>' \
     --data '{
      "name": "test_1",
      "language": "English",
      "parse_type": 1,
      "parser_id": "general"
      }'
```

##### A request example specifying ingestion pipeline

:::caution WARNING
Do not include `"parser_id"` when specifying an ingestion pipeline.
:::

```bash
curl --request POST \
  --url http://{address}/api/v1/datasets \
  --header 'Content-Type: application/json' \
  --header 'Authorization: Bearer <YOUR_API_KEY>' \
  --data '{
   "name": "test-sdk",
   "language": "English",
   "parse_type": 2,
   "pipeline_id": "<PIPELINE_ID_32_HEX>"
  }'
```

##### Body parameters

- `"name"`: `string`, *Required*
  The unique name of the dataset to create. It must adhere to the following requirements:
  - Basic Multilingual Plane (BMP) only
  - Maximum 128 characters
  - Case-insensitive
  If the name is already taken, the dataset is created with a numbered suffix such as `test_1(1)`, `test_1(2)`, and so on.

- `"language"`: `string`
  Optional document/dataset language, for example: `"English"` or `"Chinese"`. Leading and trailing whitespace are stripped. After trimming, it must contain at least 1 character and at most 32 characters. The limit counts characters, not UTF-8 bytes. No restricted list of language values is enforced. If omitted, the server/database default is used.

- `"embedding_model"`: `string`
  The name of the embedding model to use. For example: `"BAAI/bge-large-zh-v1.5@BAAI"`.
  - Maximum 255 characters
  - Must follow `model_name@model_factory` format

- `"permission"`: `string`
  Specifies who can access the dataset to create. Available options:
  - `"me"`: (Default) Only you can manage the dataset.
  - `"team"`: All team members can manage the dataset.

- `"parser_id"`: `enum<string>`
  The built-in parser to use. Required when `"parse_type"` is `1`.
  - `"general"`: General (default)
  - `"qa"`: Q&A
  - `"manual"`: Manual
  - `"table"`: Table
  - `"paper"`: Paper
  - `"book"`: Book
  - `"laws"`: Laws
  - `"presentation"`: Presentation
  - `"picture"`: Picture
  - `"one"`: One
  - `"audio"`: Audio
  - `"email"`: Email
  - Must be omitted when `"parse_type"` is `2`.

- `"parser_config"`: `object`
  The configuration settings for the dataset parser. RAGFlow 1.0 stores parser settings per ingestion-pipeline component; use component-scoped keys (keys containing `:`) as returned by the API. Legacy flat keys are ignored.

- `"parse_type"`: `int`, *Required*
  The parser selection mode:
  - `1`: BuiltIn. Requires `"parser_id"`.
  - `2`: Pipeline. Requires `"pipeline_id"`.

- `"pipeline_id"`: `string`
  The ingestion pipeline ID. Can be found in the corresponding URL in the RAGFlow UI.
  - Required when `"parse_type"` is `2`.
  - Must be a 32-character lowercase hexadecimal string, e.g., `"d0bebe30ae2211f0970942010a8e0005"`.
  - Must be omitted when `"parse_type"` is `1`.

:::caution WARNING
`"parse_type"` is required when creating a dataset. Choose exactly one mode:

- `"parse_type": 1` with `"parser_id"` for a builtin parser.
- `"parse_type": 2` with `"pipeline_id"` for an ingestion pipeline.

`"chunk_method"`, `"avatar"`, `"description"`, and `"auto_metadata_config"` are not accepted by the RAGFlow 1.0 create endpoint. Use `"parser_id"` instead of `"chunk_method"`; set avatar and description with the update endpoint, and metadata configuration with the metadata endpoint.

### List datasets

**GET** `/api/v1/datasets?page={page}&page_size={page_size}&orderby={orderby}&desc={desc}&sort={sort}&name={dataset_name}&id={dataset_id}&include_parsing_status={include_parsing_status}`

Lists datasets.

#### Request

- Method: GET
- URL: `/api/v1/datasets?page={page}&page_size={page_size}&orderby={orderby}&desc={desc}&sort={sort}&name={dataset_name}&id={dataset_id}&include_parsing_status={include_parsing_status}`
- Headers:
  - `'Authorization: Bearer <YOUR_API_KEY>'`

##### Request example

```bash
curl --request GET \
     --url http://{address}/api/v1/datasets?page={page}&page_size={page_size}&orderby={orderby}&desc={desc}&sort={sort}&name={dataset_name}&id={dataset_id} \
     --header 'Authorization: Bearer <YOUR_API_KEY>'
```

```bash
# List datasets with parsing status
curl --request GET \
     --url 'http://{address}/api/v1/datasets?include_parsing_status=true' \
     --header 'Authorization: Bearer <YOUR_API_KEY>'
```

##### Query parameters

- `page`
  Specifies the page on which the datasets will be displayed. Defaults to `1`.
- `page_size`
  The number of datasets on each page. Defaults to `30`.
- `orderby`
  The field by which datasets should be sorted. Available options:
  - `create_time` (default)
  - `update_time`
- `desc`
  Indicates whether the retrieved datasets should be sorted in descending order. Defaults to `true`.
- `sort`
  Orders by several fields at once, written as `column:direction` terms separated by commas, such as `name:asc,create_time:desc`. A term with no direction is ascending. `sort` takes precedence over `orderby` and `desc`, which keep working on their own. A term naming a field this list does not sort by is skipped. When `sort` yields no terms at all, `orderby` and `desc` decide the order. When it yields terms whose fields are all skipped, the result is ordered by `create_time` in the direction of the first term, and the older pair is not read.
- `name`
  The name of the dataset to retrieve.
- `id`
  The ID of the dataset to retrieve.
- `include_parsing_status`
  Whether to include document parsing status counts in the response. Defaults to `false`. When set to `true`, each dataset object in the response will include the following additional fields:
  - `unstart_count`: Number of documents not yet started parsing.
  - `running_count`: Number of documents currently being parsed.
  - `cancel_count`: Number of documents whose parsing was canceled.
  - `done_count`: Number of documents that have been successfully parsed.
  - `fail_count`: Number of documents whose parsing failed.

### Apply dataset parser settings to existing documents

**POST** `/api/v1/datasets/{dataset_id}/documents/apply-parser-config`

Applies the dataset's saved parser settings to all its existing documents. Save the dataset first with `PUT /api/v1/datasets/{dataset_id}`. This operation requires dataset update permission, takes no request body, and reads the current saved settings on the server.

File-specific parser overrides are replaced. Parser selection and pipeline version are updated together with `parser_config`, using the same file-type resolution as uploads (including dedicated image, audio, presentation, and email parsers). A document assigned to a custom pipeline inherits the dataset's version pin; built-in parsers have no version pin.

Existing chunks, indexes, metadata values, counters, and parsing progress are preserved. This endpoint does not start parsing or delete prior results. Manually re-parse the files to regenerate their content with the saved settings.

All document changes are committed in one transaction. If any document has a queued, running, stopping, or unrecognized ingestion status, the operation fails with response body code `409` and no document changes are committed. Stop parsing or wait for completion before retrying. A database failure also rolls back all document updates. The dataset settings saved by the preceding PUT remain saved if this operation fails.

Repeating this operation against unchanged dataset settings leaves already matching documents unchanged. An empty dataset succeeds with all counts set to zero.

#### Request example

```bash
curl --request POST \
     --url http://{address}/api/v1/datasets/{dataset_id}/documents/apply-parser-config \
     --header 'Authorization: Bearer <YOUR_API_KEY>'
```

#### Response example

```json
{
    "code": 0,
    "message": "Parser settings applied. Re-parse files manually to update their content.",
    "data": {
        "dataset_id": "...",
        "total_documents": 120,
        "updated_documents": 115,
        "unchanged_documents": 5
    }
}
```

### Update document

**PATCH** `/api/v1/datasets/{dataset_id}/documents/{document_id}`

Updates configurations for a specified document.

Saving parser settings preserves existing chunks, chunk images, counters, and parsing progress. The saved settings take effect on the next parse; this update does not start parsing or delete existing results. Use the document parse action to clear existing chunks and re-parse with the saved settings.

              }
            ]
          }
     }'
```

##### Body parameters

- `"question"`: `string`, *Required*
  The user query or query keywords.
- `"dataset_ids"`: `list[string]`, *Required*
  The IDs of the datasets to search. At least one dataset ID must be provided.
- `"document_ids"`: `list[string]`
  Limits the search to specific documents within the datasets specified by `"dataset_ids"`. Ensure that all selected documents use the same embedding model. Defaults to an empty list.
- `"page"`: `integer`
  Specifies the page on which the chunks will be displayed. Defaults to `1`.
- `"page_size"`
  The maximum number of chunks on each page. Defaults to `30`.
- `"similarity_threshold"`
  The minimum similarity score. Defaults to `0.2`.
- `"keywords_similarity_weight"`: `float`
  The weight of term similarity. Defaults to `0.7`; the vector cosine similarity weight is calculated as `1 - keywords_similarity_weight`.
- `"vector_similarity_weight"`: `float`
  Legacy fallback used when `"keywords_similarity_weight"` is omitted. If both fields are provided, they must sum to `1`.
- `"top_k"`: `integer`
  **Deprecated.** An alias for `"knn_top_k"`. If both parameters are provided, `"knn_top_k"` takes precedence.
- `"knn_top_k"`: `integer`
  The number of chunks engaged in vector cosine computation. Defaults to `1024`.
- `"knn_num_candidates"`: `integer`
  The number of approximate nearest-neighbor candidates considered for vector search. It must be greater than or equal to `"knn_top_k"`. Defaults to the greater of `2048` and `"knn_top_k"`. This parameter currently applies only to Elasticsearch.
- `"rerank_candidates_count"`: `integer`
  The number of initial retrieval candidates to rank. It must be at least `"page"` multiplied by `"page_size"`. Defaults to `64`.
- `"include_knowledge_compilation"`: `boolean`
  Whether to include knowledge-compilation chunks in the results. Defaults to `true`.
- `"knowledge_compilation_scope"`: `string`
  Selects which searchable knowledge-compilation chunks to include: `"dataset"` for dataset artifacts, `"document"` for document artifacts, or `"all"` for both. Defaults to `"dataset"` when omitted, `null`, or an empty string. Ordinary source chunks remain eligible. When `"include_knowledge_compilation"` is `false`, all compiled chunks are excluded regardless of scope. Unsupported scope values and non-string values return an argument error. Intermediate wiki rows and disabled chunks remain excluded.
  With `"document_ids"` or metadata filtering, document artifacts and source chunks are limited to the selected documents; dataset artifacts must reference a selected document in their `source_doc_ids`. This parameter is also supported by `POST /api/v1/datasets/search` and `POST /api/v1/datasets/{dataset_id}/search`.
- `"use_kg"`: `boolean`
  Defaults to `false`. For this endpoint (`POST /api/v1/retrieval`), setting this to `true` does not enable multi-hop graph retrieval; the request continues through ordinary hybrid retrieval. The same limitation applies to `POST /api/v1/datasets/search` and `POST /api/v1/datasets/{dataset_id}/search`. To control whether searchable knowledge-compilation chunks are included in ordinary retrieval, use `"include_knowledge_compilation"` and `"knowledge_compilation_scope"`. Knowledge graph generation and viewing through Knowledge Compilation are separate capabilities.
- `"rerank_id"`: `string`
  The ID of the rerank model.
- `"keyword"`: `boolean`
  Indicates whether to enable keyword-based matching:
  - `true`: Enable keyword-based matching.
  - `false`: Disable keyword-based matching (default).
- `"highlight"`: `boolean`
  Specifies whether to enable highlighting of matched terms in the results:
  - `true`: Enable highlighting of matched terms.
  - `false`: Disable highlighting of matched terms (default).
- `"cross_languages"`: (*Body parameter*) `list[string]`
  The languages that should be translated into, in order to achieve keywords retrievals in different languages.
- `"metadata_condition"`: `object`
  The metadata condition used for filtering chunks:
  - `"logic"`: `string`
    - `"and"`: Return only results that satisfy *every* condition (default).
    - `"or"`: Return results that satisfy *any* condition.
  - `"conditions"`: `array`
    A list of metadata filter conditions.
    - `"name"`: `string` - The metadata field name to filter by, e.g., `"author"`, `"company"`, `"url"`. Ensure this parameter before use. See [Set metadata](../guides/dataset/metadata_management.md) for details.
    - `comparison_operator`: `string` - The comparison operator. Can be one of:
      - `"contains"`
      - `"not contains"`
      - `"start with"`
      - `"empty"`
      - `"not empty"`
      - `"="`
      - `"≠"`
      - `">"`
      - `"<"`
      - `"≥"`
      - `"≤"`
    - `"value"`: `string` - The value to compare.

- Headers:
  - `'Content-Type: application/json'`
  - `'Authorization: Bearer <YOUR_API_KEY>'`
- Body:
  - `"name"`: `string`
  - `"icon"`: `string`
  - `"dataset_ids"`: `list[string]`
  - `"llm_id"`: `string`
  - `"llm_setting"`: `object`
  - `"prompt_config"`: `object`

##### Request example

```shell
curl --request POST \
     --url http://{address}/api/v1/chats \
     --header 'Content-Type: application/json' \
     --header 'Authorization: Bearer <YOUR_API_KEY>' \
     --data '{
    "dataset_ids": ["0b2cbc8c877f11ef89070242ac120005"],
    "name":"new_chat_1"
}'
```

##### Body parameters

- `"name"`: `string`, *Required*
  The name of the chat assistant.
  If a chat assistant with the same name already exists, the new one gets a numbered suffix such as `new_chat_1(1)`.
- `"icon"`: `string`
  Base64 encoding of the avatar.
- `"dataset_ids"`: `list[string]`
  The unique identifiers for the associated datasets. If omitted or set to `[]`, an empty chat assistant is created; datasets can be attached at a later time.
- `"llm_id"`: `string`
  The identifier of the chat model. If not specified, the system defaults to the user's pre-configured chat model.
- `"llm_setting"`: `object`
  A configuration object defining the LLM parameters for the assistant. The `llm_setting` object may contain the following attributes:
  - `"model_type"`: `string`
    A model type specifier. Only `"chat"` and `"image2text"` are recognized; any other inputs, or when omitted, are treated as `"chat"`.
  - `"temperature"`: `float`
    Controls the randomness of the model's predictions. A lower temperature results in more conservative responses, while a higher temperature yields more creative and diverse responses. Defaults to `0.1`.
  - `"top_p"`: `float`
    Also known as "nucleus sampling", this parameter sets a threshold to select a smaller set of words to sample from. It focuses on the most likely words, cutting off the less probable ones. Defaults to `0.3`
  - `"presence_penalty"`: `float`
    This discourages the model from repeating the same information by penalizing words that have already appeared in the conversation. Defaults to `0.4`.
  - `"frequency penalty"`: `float`
    Similar to the presence penalty, this reduces the model's tendency to repeat the same words frequently. Defaults to `0.7`.
- `"prompt_config"`: `object`
  Instructions for the LLM to follow. A `prompt_config` object may contain the following attributes:
  - `"system"`: `string` The prompt content.
  - `"prologue"`: `string` The opening greeting for the user.
  - `"parameters"`: `object[]` This argument lists the variables to use in the system prompt. Note that:
    - `"knowledge"` is a reserved variable, which represents the retrieved chunks.
    - All the variables in `"system"` should be curly bracketed.
  - `"empty_response"`: `string` If nothing is retrieved in the dataset for the user's question, this will be used as the response. To allow the LLM to improvise when nothing is found, leave this blank.
  - `"quote"`: `boolean` Whether the source of text should be displayed. Defaults to `true`.
  - `"tts"`: `boolean`
  - `"refine_multiturn"`: `boolean`
  - `"reasoning"`: `boolean`
  - `"cross_languages"`: `list[string]`
  - `"web_search_provider"`: `string` The web search service to use. Supported values are `"brave"`, `"exa"`, `"firecrawl"`, `"linkup"`, `"parallel"`, `"querit"`, `"search1api"`, `"searchapi"`, `"serply"`, `"tavily"`, and `"youcom"`. If omitted, Tavily is selected only when `"tavily_api_key"` is configured; otherwise web search is disabled.
  - `"tavily_api_key"`: `string`
  - `"brave_api_key"`: `string` The Brave Search API key. Set `web_search_provider` to `"brave"` when using this field.
  - `"exa_api_key"`: `string` The Exa API key. Set `web_search_provider` to `"exa"` when using this field.
  - `"firecrawl_api_key"`: `string` The [Firecrawl](https://www.firecrawl.dev/search) API key. Set `web_search_provider` to `"firecrawl"` when using this field. See the [Firecrawl Search API reference](https://docs.firecrawl.dev/api-reference/endpoint/search) for details.
  - `"linkup_api_key"`: `string` The Linkup API key. Set `web_search_provider` to `"linkup"` when using this field.
  - `"parallel_api_key"`: `string` The Parallel API key. Set `web_search_provider` to `"parallel"` when using this field.
  - `"querit_api_key"`: `string` The Querit API key. Set `web_search_provider` to `"querit"` when using this field.
  - `"search1api_api_key"`: `string` The [Search1API](https://s1.dev) API key. Set `web_search_provider` to `"search1api"` when using this field. See the [Search1API documentation](https://s1.dev/docs/basic/search) for details.
  - `"searchapi_api_key"`: `string` The [SearchApi](https://www.searchapi.io) API key. Set `web_search_provider` to `"searchapi"` when using this field. Results come from its Google engine. See the [SearchApi Google documentation](https://www.searchapi.io/docs/google) for details.
  - `"serply_api_key"`: `string` The [Serply](https://serply.io) API key. Set `web_search_provider` to `"serply"` when using this field. See the [Serply documentation](https://serply.io/docs) for details.
  - `"youcom_api_key"`: `string` The You.com API key. Set `web_search_provider` to `"youcom"` when using this field. Optional: You.com serves a rate-limited keyless endpoint, so `"youcom"` works with this field omitted, and a key lifts those limits.
- `"similarity_threshold"`: `float`
- `"keywords_similarity_weight"`: `float`
- `"vector_similarity_weight"`: `float`, legacy fallback. If both weights are provided, they must sum to `1`.
- `"top_n"`: `int`

          "rerank_id":""
     }'
```

#### Parameters

- `chat_id`: (*Path parameter*)
  The ID of the chat assistant to update.
- `"name"`: (*Body parameter*), `string`, *Required*
  The revised name of the chat assistant.
- `"icon"`: (*Body parameter*), `string`
  Base64 encoding of the avatar.
- `"dataset_ids"`: (*Body parameter*), `list[string]`
  The IDs of the associated datasets.
- `"llm_id"`: (*Body parameter*), `string`
  The chat model name. If not set, the user's default chat model is used.
- `"llm_setting"`: (*Body parameter*), `object`
  The LLM settings for the chat assistant. An `llm_setting` object contains the following attributes:
  - `"model_type"`: `string`
    A model type specifier. Supported values are `"chat"` and `"image2text"`. If the field is omitted or an unrecognized value is provided, it defaults to `"chat"`.
  - `"temperature"`: `float`
    Controls the randomness of the model's predictions. A lower temperature results in more conservative responses, while a higher temperature yields more creative and diverse responses. Defaults to `0.1`.
  - `"top_p"`: `float`
    Also known as "nucleus sampling", this parameter sets a threshold to select a smaller set of words to sample from. It focuses on the most likely words, cutting off the less probable ones. Defaults to `0.3`
  - `"presence_penalty"`: `float`
    This discourages the model from repeating the same information by penalizing words that have already appeared in the conversation. Defaults to `0.4`.
  - `"frequency penalty"`: `float`
    Similar to the presence penalty, this reduces the model's tendency to repeat the same words frequently. Defaults to `0.7`.
- `"prompt_config"`: (*Body parameter*), `object`
- `"similarity_threshold"`: (*Body parameter*), `float`
- `"keywords_similarity_weight"`: (*Body parameter*), `float`
- `"vector_similarity_weight"`: (*Body parameter*), `float`, legacy fallback. If both weights are provided, they must sum to `1`.
- `"top_n"`: (*Body parameter*), `int`
- `"top_k"`: (*Body parameter*), `int`
- `"rerank_id"`: (*Body parameter*), `string`

For `PUT` requests, any fields omitted from the request body are reset to their server-side default values.

#### Response

Success: returns the full updated chat assistant object.

### List chat assistants

**GET** `/api/v1/chats?page={page}&page_size={page_size}&orderby={orderby}&desc={desc}&sort={sort}&keywords={keywords}&owner_ids={owner_id}&name={chat_name}&id={chat_id}`

Lists chat assistants.

#### Request

- Method: GET
- URL: `/api/v1/chats?page={page}&page_size={page_size}&orderby={orderby}&desc={desc}&sort={sort}&keywords={keywords}&owner_ids={owner_id}&name={chat_name}&id={chat_id}`
- Headers:
  - `'Authorization: Bearer <YOUR_API_KEY>'`

##### Request example

```bash
curl --request GET \
     --url http://{address}/api/v1/chats?page={page}&page_size={page_size}&orderby={orderby}&desc={desc}&sort={sort}&keywords={keywords}&owner_ids={owner_id}&name={chat_name}&id={chat_id} \
     --header 'Authorization: Bearer <YOUR_API_KEY>'
```

##### Query parameters

- `page`: `integer`
  Specifies the page on which the chat assistants will be displayed. Defaults to `1`.
- `page_size`: `integer`
  The number of chat assistants on each page. Defaults to `30`.
- `orderby`: `string`
  The attribute by which the results are sorted. Available options:
  - `create_time` (default)
  - `update_time`
- `desc`: `boolean`
  Indicates whether the retrieved chat assistants should be sorted in descending order. Defaults to `true`.
- `sort`: `string`
  Orders by several fields at once, written as `column:direction` terms separated by commas, such as `name:asc,create_time:desc`. A term with no direction is ascending. `sort` takes precedence over `orderby` and `desc`, which keep working on their own. A term naming a field this list does not sort by is skipped. When `sort` yields no terms at all, `orderby` and `desc` decide the order. When it yields terms whose fields are all skipped, the result is ordered by `create_time` in the direction of the first term, and the older pair is not read.
- `keywords`: `string`
  Case-insensitive fuzzy match against chat assistant names.
- `owner_ids`: `string` (repeatable)
  Filter by owner tenant IDs. Can be specified multiple times: `?owner_ids=id1&owner_ids=id2`.
- `id`: `string`
  The ID of the chat assistant to retrieve with exact match.
- `name`: `string`
  The name of the chat assistant to retrieve with exact match.

When `id` or `name` is provided, exact filtering takes precedence over `keywords`.

- `include_reference`: (*Query parameter*) `boolean`, defaults to `false`.
  Include reference objects in answer messages when history is included.
- `include_prompt`: (*Query parameter*) `boolean`, defaults to `false`.
  Include recorded prompt strings in answer messages when history is included.

When `sort` yields no terms at all, `orderby` and `desc` decide the order. When it yields terms whose fields are all skipped, the result is ordered by `create_time` in the direction of the first term, and the older pair is not read.
- `name`: (*Query parameter*) `string`
  The name of the chat session to retrieve.
- `id`: (*Query parameter*), `string`
  The ID of the chat session to retrieve.
- `user_id`: (*Query parameter*), `string`
  The optional user-defined ID passed in when creating session.

### Get chat assistant's session

**GET** `/api/v1/chats/{chat_id}/sessions/{session_id}`

Gets a specific session of a specified chat assistant, including its messages, references, and avatar.

Completed assistant entries in `messages` include recorded `usage` (an object
with `prompt_tokens`, `completion_tokens`, and `total_tokens`) and `elapsed_ms`
(a number in milliseconds). Large answer fields are opt-in:

- `include_reference`: boolean, defaults to `false`. Set to `true` to return a
  `reference` object containing `chunks` and `doc_aggs` inside each answer.
- `include_prompt`: boolean, defaults to `false`. Set to `true` to return the
  recorded prompt string inside each answer.

These query parameters apply only to chat and agent session list and detail
endpoints. Fields omitted by these flags are excluded from SQL as well as the
response. Invalid boolean values return an argument error on these read endpoints.
Create, update, message deletion, and feedback endpoints ignore these query
parameters and omit `reference` and `prompt` from their responses.
There is no session-level reference array.

The UI requests references for citations and source previews, and prompts for
answer details. Older messages omit unavailable usage, timing, or prompt fields.
Generation history SQL omits `reference`, `prompt`, `usage`, and `elapsed_ms`, and
these fields are excluded from LLM input. Agentic answers have no recorded prompt.

### Converse with chat assistant

**POST** `/api/v1/chat/completions`

Starts a chat completion request. The same endpoint supports three modes:

:::caution REMOVED ALIAS
`POST /api/v1/chats/{chat_id}/completions` is not available in 1.0. Use this endpoint instead.
:::

- No `chat_id`: talk directly with the tenant's default chat model.
- With `chat_id` but no `session_id`: use that chat's configuration and automatically create a new session.
- With both `chat_id` and `session_id`: continue an existing chat session.

:::tip NOTE

- In streaming mode, not all responses include a reference, as this depends on the system's judgment.
- In streaming mode, the last message is an empty message:

  ```json
  data:
  {
    "code": 0,
    "data": true
  }
  ```

:::

#### Request

- Method: POST
- URL: `/api/v1/chat/completions`
- Headers:
  - `'Content-Type: application/json'`
  - `'Authorization: Bearer <YOUR_API_KEY>'`
- Body:

  - `"question"`: `string`
  - `"messages"`: `list[object]`
  - `"store_history_messages"`: `boolean` (optional)
  - `"stream"`: `boolean`
  - `"chat_id"`: `string` (optional)
  - `"session_id"`: `string` (optional)
  - `"llm_id"`: `string` (optional)
  - `"legacy"`: `boolean` (optional)

##### Request example

```bash
curl --request POST \
     --url http://{address}/api/v1/chat/completions \
     --header 'Content-Type: application/json' \
     --header 'Authorization: Bearer <YOUR_API_KEY>' \
     --data-binary '
     {
          "messages": [
              {
                  "role": "user",
                  "content": "Who are you?"
              }
          ]
     }'
```

```bash
curl --request POST \
     --url http://{address}/api/v1/chat/completions \
     --header 'Content-Type: application/json' \
     --header 'Authorization: Bearer <YOUR_API_KEY>' \
     --data-binary '
     {
          "chat_id": "{chat_id}",
          "stream": true,
          "session_id":"9fa7691cb85c11ef9c5f0242ac120005",
          "messages": [
              {
                  "role": "user",
                  "content": "Who are you?"
              }
          ]
     }'
```

##### Body parameters

- `"question"`: `string`
  The user question. Provide either `"question"` or `"messages"`. When both are provided, `"question"` takes precedence unless `"store_history_messages"` is `false`.
- `"messages"`: `list[object]`
  The conversation messages. The last message must have the `user` role. When `"store_history_messages"` is `false`, this field is required and the full message list is used instead of `"question"`.
- `"store_history_messages"`: `boolean`
  Controls whether conversation history is stored. It defaults to `true`; the only supported explicit value is `false`. When set to `false`, `"messages"` is required and the supplied message list is processed without storing it as conversation history.
- `"stream"`: `boolean`
  Enables streaming output:
  - `true`: Enable streaming (default).
  - `false`: Disable streaming.
- `"chat_id"`
  Optional chat assistant ID. If omitted, the tenant's default chat model is used directly.
- `"session_id"`
  Optional session ID. If `chat_id` is provided but `session_id` is omitted, a new session will be generated automatically.
- `"llm_id"`: `string`
  Optional model override when a specific chat model should be used for this request.
- `"legacy"`: `boolean`
  Defaults to `false`. Enables backward compatibility with RAGFlow v0.23.0 for streaming responses. When set to `true`:
  - Cumulative output: The `"answer"` field in each chunk returns the entire text generated so far, rather than just the new tokens (deltas).
  - No reasoning markers: The `start_to_think` and `end_to_think` signals are stripped from the stream.

### Converse with agent

**POST** `/api/v1/agents/chat/completions`

Asks a specified agent a question to start an AI-powered conversation.

Uses a single completion endpoint for all agent conversations.

:::caution REMOVED ALIAS
`POST /api/v1/agents/{agent_id}/completions` is not available in 1.0. Use this endpoint instead.
:::

#### Request

- Method: POST
- URL: `/api/v1/agents/chat/completions`
- Headers:
  - `'Content-Type: application/json'`
  - `'Authorization: Bearer <YOUR_API_KEY>'`

#### Standard mode

Use this mode for the native agent API.

##### Body

- `"agent_id"`: `string`
- `"question"`: `string`
- `"stream"`: `boolean`
- `"session_id"`: `string` (optional)
- `"inputs"`: `object` (optional)
- `"files"`: `list[object]` (optional)
- `"user_id"`: `string` (optional)
- `"return_trace"`: `boolean` (optional, default `false`)
- `"chat_template_kwargs"`: `object` (optional)

#### Streaming events to handle

When `stream=true`, the server sends Server-Sent Events (SSE). A client should handle these events:

- `message`: Streaming content from the **Message** components.
- `message_end`: End of a **Message** component, which may include `reference` or `attachment`.
- `node_finished`: A component finishes. `data.inputs`, `data.outputs`, `data.error`, and `data.elapsed_time` describe the node result. If `return_trace=true`, the same event also contains `data.trace`.

The stream terminates with `[DONE]`.

:::info IMPORTANT
You can include custom parameters in the request body, but they must be defined in the [Begin](../guides/agent/agent_workflow/basic_component.md) component first.
:::

##### Request examples

If the **Begin** component does not take parameters:

```bash
curl --request POST \
     --url http://{address}/api/v1/agents/chat/completions \
     --header 'Content-Type: application/json' \
     --header 'Authorization: Bearer <YOUR_API_KEY>' \
     --data-binary '
     {
        "agent_id": "AGENT_ID",
        "question": "Hello",
        "stream": false
     }'
```

- If the **Begin** component takes parameters, include their values in the body of `"inputs"` as follows:

```bash
curl --request POST \
     --url http://{address}/api/v1/agents/chat/completions \
     --header 'Content-Type: application/json' \
     --header 'Authorization: Bearer <YOUR_API_KEY>' \
     --data-binary '
     {
        "agent_id": "AGENT_ID",
        "question": "",
        "stream": false,
        "inputs": {
            "line_var": {
                "type": "line",
                "value": "I am line_var"
            },
            "int_var": {
                "type": "integer",
                "value": 1
            },
            "paragraph_var": {
                "type": "paragraph",
                "value": "a\nb\nc"
            },
            "option_var": {
                "type": "options",
                "value": "option 2"
            },
            "boolean_var": {
                "type": "boolean",
                "value": true
            }
        }
     }'
```

To continue an existing session:

```bash
curl --request POST \
     --url http://{address}/api/v1/agents/chat/completions \
     --header 'Content-Type: application/json' \
     --header 'Authorization: Bearer <YOUR_API_KEY>' \
     --data-binary '
     {
        "agent_id": "AGENT_ID",
        "question": "Hello again",
        "stream": true,
        "session_id": "cb2f385cb86211efa36e0242ac120005"
     }'
```

##### Body parameters

- `"agent_id"`: `string`, *Required*
  The ID of the associated agent.
- `"question"`: `string`
  The question to start an AI-powered conversation.
- `"stream"`: `boolean`
  Indicates whether to output responses in a streaming way:
  - `true`: Enable streaming (default).
  - `false`: Disable streaming.
- `"session_id"`
  The ID of the session. If it is not provided, a new session will be generated.
- `"inputs"`: `object`
  Values for variables defined in the **Begin** component. Each variable value must be an object containing a `"value"` field and may include a `"type"` field.
- `"files"`: `array`
  File descriptors returned by the Agent file upload endpoint. RAGFlow makes the uploaded files available to the Agent through `sys.files`.
- `"user_id"`: `string`
  The optional user-defined ID. Valid *only* when no `session_id` is provided.
- `"chat_template_kwargs"`: `object`
  Optional passthrough parameters for the underlying LLM's chat template. Commonly used to toggle thinking/reasoning modes on supported models (e.g., `{"enable_thinking": false}`).

:::tip NOTE
Before sending a file in a conversation, upload it as multipart form data with the field name `file` to `POST http://{address}/api/v1/agents/{agent_id}/upload`. The endpoint accepts one or more files and returns a file descriptor for one file or an array of descriptors for multiple files. Pass the returned descriptor or descriptors in the `files` array of the conversation request.
:::

##### Response

Standard mode stream:

```json
data: {
    "event": "message",
    "message_id": "cecdcb0e83dc11f0858253708ecb6573",
    "created_at": 1756364483,
    "task_id": "d1f79142831f11f09cc51795b9eb07c0",
    "data": {
        "content": "Hello"
    },
    "session_id": "cd097ca083dc11f0858253708ecb6573"
}

data: {

}

data:[DONE]
```

When `extra_body.reference_metadata.include` is `true`, each reference chunk may include a `document_metadata` object.

Standard mode non-stream:

```json
{
    "code": 0,
    "data": {
        "data": {
            "content": "Hello",
            "reference": {},
            "trace": []
        },
        "message_id": "c4692a2683d911f0858253708ecb6573",
        "session_id": "c39f6f9c83d911f0858253708ecb6573",
        "task_id": "d1f79142831f11f09cc51795b9eb07c0"
    }
}
```

## AGENT MANAGEMENT

---

### List agents

**GET** `/api/v1/agents`

Lists agents and compilation template groups accessible to the current user.

#### Request

- Method: GET
- URL: `/api/v1/agents`
- Headers:
  - `'Authorization: Bearer <YOUR_API_KEY>'`

##### Request example

```bash
curl --request GET \
     --url 'http://{address}/api/v1/agents?page=1&page_size=30&orderby=create_time&desc=true&keywords=example' \
     --header 'Authorization: Bearer <YOUR_API_KEY>'
```

##### Query parameters

- `page`: `integer`
  Specifies the page on which the agents will be displayed. Defaults to `1`.
- `page_size`: `integer`
  The number of agents on each page. Defaults to `30`.
- `orderby`: `string`
  The attribute by which the results are sorted. Available options:
  - `create_time` (default)

- `sort`: `string`
  Orders by several fields at once, written as `column:direction` terms separated by commas, such as `name:asc,create_time:desc`. A term with no direction is ascending. `sort` takes precedence over `orderby` and `desc`, which keep working on their own. A term naming a field this list does not sort by is skipped. When `sort` yields no terms at all, `orderby` and `desc` decide the order. When it yields terms whose fields are all skipped, the result is ordered by `create_time` in the direction of the first term, and the older pair is not read.
- `keywords`: `string`
  Fuzzy-searches agents by title.

### Delete agent version

**DELETE** `/api/v1/agents/{agent_id}/versions/{version_id}`

Deletes one saved version belonging to the specified agent. The current agent
and its other saved versions remain unchanged. This also allows deleting the
last saved version.

#### Request

- Method: DELETE
- URL: `/api/v1/agents/{agent_id}/versions/{version_id}`
- Headers:
  - `'Authorization: Bearer <YOUR_API_KEY>'`
- Body: none.

##### Request example

```bash
curl --request DELETE \
     --url http://{address}/api/v1/agents/{agent_id}/versions/{version_id} \
     --header 'Authorization: Bearer <YOUR_API_KEY>'
```

##### Path parameters

- `agent_id`: `string`, required. The agent whose history contains the version.
- `version_id`: `string`, required. The saved version to delete.

#### Response

Success:

```json
{
    "code": 0,
    "data": true,
    "message": "success"
}
```

The caller must have permission to edit the agent. A missing or inaccessible
agent, a missing version, or a version belonging to a different agent returns
business code `103` with the message `"Make sure you have permission to access the agent."`.

---

### Apply agent version

**POST** `/api/v1/agents/{agent_id}/versions/{version_id}/apply`

Restores the saved version's workflow DSL into the current agent as an unpublished
draft. The agent's title, description, ownership, sharing, and other metadata are
preserved. The source version and existing history are retained. The restored DSL
passes the same validation and normalization as an ordinary agent update.

Applying saves the restored workflow to version history using the normal save
behavior: it creates a new draft version when the latest DSL differs or the
latest version is published, and refreshes an identical latest draft. Publish
the agent separately when the restored workflow is ready for release.

#### Request

- Method: POST
- URL: `/api/v1/agents/{agent_id}/versions/{version_id}/apply`
- Headers:
  - `'Authorization: Bearer <YOUR_API_KEY>'`
- Body: none.

##### Request example

```bash
curl --request POST \
     --url http://{address}/api/v1/agents/{agent_id}/versions/{version_id}/apply \
     --header 'Authorization: Bearer <YOUR_API_KEY>'
```

##### Path parameters

- `agent_id`: `string`, required. The agent to update.
- `version_id`: `string`, required. A saved version belonging to that agent.

#### Response

Success:

```json
{
    "code": 0,
    "data": true,
    "message": "success"
}
```

The caller must have permission to edit the agent. A missing or inaccessible
agent, a missing version, or a version belonging to a different agent returns
business code `103` with the message `"Make sure you have permission to access the agent."`.
A version without a DSL or a workflow that fails validation returns business
code `102`; the current agent and its history remain unchanged.

This is a fundamental question about personal identity.\n\n2. **Decompose the Request**: The request is quite simple and doesn't require complex decomposition. The core task is to provide an answer that identifies the user in some capacity.\n\n3. **Execute the Subtask**:\n   - **Identify the nature of the question**: The user is seeking to understand their own existence or their sense of self.\n   - **Assess the context**: The context is not explicitly given, so the response will be general.\n   - **Provide a response**: The answer should acknowledge the user's inquiry into their identity.\n\n4. **Validate Accuracy and Consistency**: The response should be consistent with the general understanding of the question. Since the user has not provided specific details about their identity, the response should be broad and open-ended.\n\n5. **Summarize the Final Result**: The user is asking \"who am I?\" which is an inquiry into their own identity. The answer is that the user is the individual who is asking the question. Without more specific information, a detailed description of their identity cannot be provided.\n\nSo, the final summary would be:\n\nThe user is asking the question \"who am I?\" to seek an understanding of their own identity.

Inside, the juicy yellow flesh surrounds a fibrous core.\nGrowth: Unlike most fruits, pineapples do not grow on trees. They grow from a central stem as a composite fruit, meaning they are formed from many individual berries that fuse together around the core. They grow on a short, leafy plant close to the ground.\nUses: Pineapples are eaten fresh, cooked, grilled, juiced, or canned. They are a popular ingredient in desserts, fruit salads, savory dishes (like pizzas or ham glazes), smoothies, and cocktails.\nNutrition: They are a good source of Vitamin C, manganese, and contain an enzyme called bromelain, which aids in digestion and can tenderize meat.\nSymbolism: The pineapple is a traditional symbol of hospitality and welcome in many cultures.\nAre you asking about the fruit itself, or its use in a specific context?",

### Check system health

**GET** `/api/v1/system/healthz`

Check the health status of RAGFlow's dependencies: metadata database, Kvrocks cache, document engine, object storage, and NATS message queue.

:::caution REMOVED ALIAS
`GET /v1/system/healthz` is not available in 1.0. Use this endpoint instead.
:::

#### Request

- Method: GET
- URL: `/api/v1/system/healthz`
- Headers:
  - 'Content-Type: application/json'
  (no Authorization required)

##### Request example

```bash
curl --request GET \
     --url http://{address}/api/v1/system/healthz \
     --header 'Content-Type: application/json'
```

---

#### Responses

- **200 OK** – All services healthy

```http
HTTP/1.1 200 OK
Content-Type: application/json

{
  "db": "ok",
  "redis": "ok",
  "doc_engine": "ok",
  "storage": "ok",
  "message_queue": "ok",
  "status": "ok"
}
```

- **500 Internal Server Error** – At least one service unhealthy

```http
HTTP/1.1 500 INTERNAL SERVER ERROR
Content-Type: application/json

{
  "db": "ok",
  "redis": "nok",
  "doc_engine": "ok",
  "storage": "ok",
  "message_queue": "ok",
  "status": "nok",
  "_meta": {
    "redis": {
      "elapsed": "5.2",
      "error": "Lost connection!"
    }
  }
}
```

Explanation:

- Each service is reported as "ok" or "nok".
- The `redis` field reports the Redis-compatible Kvrocks cache; `message_queue` reports the NATS connection.
- The top-level `status` reflects overall health.
- If any service is "nok", detailed error info appears in `_meta`.

```

##### Query parameters

- `parent_id`: `string`
  The folder ID to list files from. If not specified, the root folder is used by default.
- `keywords`: `string`
  Search keyword to filter files by name.
- `page`: `integer`
  Specifies the page on which the files will be displayed. Defaults to `1`.
- `page_size`: `integer`
  The number of files on each page. Defaults to `15`.
- `orderby`: `string`
  The field by which files should be sorted. Available options:
  - `create_time` (default)
- `desc`: `boolean`
  Indicates whether the retrieved files should be sorted in descending order. Defaults to `true`.
- `sort`: `string`
  Orders by several fields at once, written as `column:direction` terms separated by commas, such as `name:asc,create_time:desc`. A term with no direction is ascending. `sort` takes precedence over `orderby` and `desc`, which keep working on their own. A term naming a field this list does not sort by is skipped. When `sort` yields no terms at all, `orderby` and `desc` decide the order. When it yields terms whose fields are all skipped, the result is ordered by `create_time` in the direction of the first term, and the older pair is not read.

### List search apps

**GET** `/api/v1/searches?keywords={keywords}&page={page}&page_size={page_size}&orderby={orderby}&desc={desc}&sort={sort}&owner_ids={owner_ids}`

Lists search apps for the current user.

#### Request

- Method: GET
- URL: `/api/v1/searches?keywords={keywords}&page={page}&page_size={page_size}&orderby={orderby}&desc={desc}&sort={sort}&owner_ids={owner_ids}`
- Headers:
  - `'Authorization: Bearer <YOUR_API_KEY>'`

##### Request example

```bash
curl --request GET \
     --url 'http://{address}/api/v1/searches?page=1&page_size=20' \
     --header 'Authorization: Bearer <YOUR_API_KEY>'
```

##### Query parameters

- `keywords`: `string`
  Search keyword to filter search apps by name.
- `page`: `integer`
  Specifies the page number. Defaults to `1`. Values less than `1` fall back to `1`.
- `page_size`: `integer`
  The number of items per page. Defaults to `30`. Values less than `1` fall back to `30`. The maximum value is `100`.
- `orderby`: `string`
  The field to sort by. Defaults to `create_time`.
- `desc`: `boolean`
  Whether to sort in descending order. Defaults to `true`.
- `sort`: `string`
  Orders by several fields at once, written as `column:direction` terms separated by commas, such as `name:asc,create_time:desc`. A term with no direction is ascending. `sort` takes precedence over `orderby` and `desc`, which keep working on their own. A term naming a field this list does not sort by is skipped. When `sort` yields no terms at all, `orderby` and `desc` decide the order. When it yields terms whose fields are all skipped, the result is ordered by `create_time` in the direction of the first term, and the older pair is not read.
- `owner_ids`: `string` (repeatable)
  Filter by owner tenant IDs. Can be specified multiple times: `?owner_ids=id1&owner_ids=id2`.

#### Response

Success:

```json
