# HTTP API

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

---

## 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 moves the public REST API from the Python backend to Go. The canonical endpoints documented below remain available.

The following changes require client updates:

| Area | RAGFlow 1.0 Go change | Client action |
|------|------------------------|---------------|
| Dataset parser selection | Dataset create and update use `parser_id`; responses use the canonical value `general` instead of the legacy `chunk_method: "naive"`. | Replace `chunk_method` with `parser_id`. For the general parser, send `"parser_id": "general"`. |
| Dataset parser configuration | Go 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 Python. | Branch on documented codes rather than exact message text. |

:::note
Go responses include `X-API-Source: go`, which can be used to verify the serving backend during rollout.

### Removed API aliases

The following paths remain available only on the Python backend. They are not registered by the RAGFlow 1.0 Go backend.

### 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' \

        "messages": [{"role": "user", "content": "Say this is a test!"}],
        "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.

  Base64 encoding of the avatar.
  - Maximum 65535 characters

- `"description"`: (*Body parameter*), `string`
  A brief description of the dataset to create.
  - Maximum 65535 characters

- `"language"`: (*Body parameter*), `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"`: (*Body parameter*), `string`

  - Maximum 255 characters
  - Must follow `model_name@model_factory` format

- `"permission"`: (*Body parameter*), `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.

- `"chunk_method"`: (*Body parameter*), `enum<string>`
  The default chunk method of the dataset to create. Mutually exclusive with `"parse_type"` and `"pipeline_id"`. If you set `"chunk_method"`, do not include `"parse_type"` or `"pipeline_id"`.
  Available options:
  - `"naive"`: General (default)
  - `"book"`: Book
  - `"email"`: Email
  - `"laws"`: Laws

- `"parser_config"`: (*Body parameter*), `object`
  The configuration settings for the dataset parser. The attributes in this JSON object vary with the selected `"chunk_method"`:
  - If `"chunk_method"` is `"naive"`, the `"parser_config"` object contains the following attributes:
    - `"auto_keywords"`: `int`
      - Defaults to `0`
      - Minimum: `0`
      - Maximum: `32`
    - `"auto_questions"`: `int`
      - Defaults to `0`
      - Minimum: `0`
      - Maximum: `10`
    - `"chunk_token_num"`: `int`
      - Defaults to `512`
      - Minimum: `1`
      - Maximum: `2048`
    - `"delimiter"`: `string`
      - Defaults to `"\n"`.
    - `"html4excel"`: `bool`
      - Whether to convert Excel documents into HTML format.
      - Defaults to `false`
    - `"layout_recognize"`: `string`
      - Defaults to `DeepDOC`
    - `"tag_kb_ids"`: `array<string>`
      - IDs of datasets to be parsed using the ​​Tag chunk method.
      - Before setting this, ensure a tag set is created and properly configured. For details, see [Use tag set](https://ragflow.io/docs/dev/use_tag_sets).
    - `"task_page_size"`: `int`
      - For PDFs only.
      - Defaults to `12`
      - Minimum: `1`
    - `"parent_child"`: `object` Parent-child chunking settings. When enabled, each chunk is further split into smaller child chunks using `children_delimiter`. At retrieval time, matched child chunks are replaced by their parent's full text before being passed to the LLM, giving precise vector matching with broader context.
      - `"use_parent_child"`: `bool` Whether to enable parent-child chunking. Defaults to `false`.
      - `"children_delimiter"`: `string` The delimiter used to split a parent chunk into child chunks. Only takes effect when `"use_parent_child"` is `true`. Defaults to `"\n"`.

- `"parse_type"`: (*Body parameter*), `int`
  The ingestion pipeline parse type identifier, i.e., the number of parsers in your **Parser** component.
  - Required (along with `"pipeline_id"`) if specifying an ingestion pipeline.
  - Must not be included when `"chunk_method"` is specified.

- `"pipeline_id"`: (*Body parameter*), `string`
  The ingestion pipeline ID. Can be found in the corresponding URL in the RAGFlow UI.
  - Required (along with `"parse_type"`) if specifying an ingestion pipeline.
  - Must be a 32-character lowercase hexadecimal string, e.g., `"d0bebe30ae2211f0970942010a8e0005"`.
  - Must not be included when `"chunk_method"` is specified.

:::caution WARNING
You can choose either of the following ingestion options when creating a dataset, but *not* both:

- Use a built-in chunk method -- specify `"chunk_method"` (optionally with `"parser_config"`).
- Use an ingestion pipeline -- specify both `"parse_type"` and `"pipeline_id"`.

If none of `"chunk_method"`, `"parse_type"`, or `"pipeline_id"` are provided, the system defaults to `chunk_method = "naive"`.

### 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>'
```

##### Request parameters

- `page`: (*Filter parameter*)
  Specifies the page on which the datasets will be displayed. Defaults to `1`.
- `page_size`: (*Filter parameter*)
  The number of datasets on each page. Defaults to `30`.
- `orderby`: (*Filter parameter*)
  The field by which datasets should be sorted. Available options:
  - `create_time` (default)
  - `update_time`
- `desc`: (*Filter parameter*)
  Indicates whether the retrieved datasets should be sorted in descending order. Defaults to `true`.
- `sort`: (*Filter parameter*)
  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`: (*Filter parameter*)
  The name of the dataset to retrieve.
- `id`: (*Filter parameter*)
  The ID of the dataset to retrieve.
- `include_parsing_status`: (*Filter parameter*)
  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.

  - `"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"
}'
```

##### Request parameters

- `"name"`: (*Body parameter*), `string`, *Required*
  The name of the chat assistant.
- `"icon"`: (*Body parameter*), `string`
  Base64 encoding of the avatar.
- `"dataset_ids"`: (*Body parameter*), `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"`: (*Body parameter*), `string`
  The identifier of the chat model. If not specified, the system defaults to the user's pre-configured chat model.
- `"llm_setting"`: (*Body parameter*), `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"`: (*Body parameter*), `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 `"tavily"`, `"firecrawl"`, `"querit"`, `"serply"`, and `"youcom"`. If omitted, Tavily is selected only when `"tavily_api_key"` is configured; otherwise web search is disabled.

  - `"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"`: (*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`.

```

#### 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>'
```

##### Request parameters

- `page`: (*Filter parameter*), `integer`
  Specifies the page on which the chat assistants will be displayed. Defaults to `1`.
- `page_size`: (*Filter parameter*), `integer`
  The number of chat assistants on each page. Defaults to `30`.
- `orderby`: (*Filter parameter*), `string`
  The attribute by which the results are sorted. Available options:
  - `create_time` (default)
  - `update_time`
- `desc`: (*Filter parameter*), `boolean`
  Indicates whether the retrieved chat assistants should be sorted in descending order. Defaults to `true`.
- `sort`: (*Filter parameter*), `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`: (*Filter parameter*), `string`
  Case-insensitive fuzzy match against chat assistant names.
- `owner_ids`: (*Filter parameter*), `string` (repeatable)
  Filter by owner tenant IDs. Can be specified multiple times: `?owner_ids=id1&owner_ids=id2`.
- `id`: (*Filter parameter*), `string`
  The ID of the chat assistant to retrieve with exact match.
- `name`: (*Filter parameter*), `string`
  The name of the chat assistant to retrieve with exact match.

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

- `desc`: (*Filter parameter*), `boolean`
  Indicates whether the retrieved sessions should be sorted in descending order. Defaults to `true`.
- `sort`: (*Filter parameter*), `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.
- `name`: (*Filter parameter*) `string`
  The name of the chat session to retrieve.
- `id`: (*Filter parameter*), `string`
  The ID of the chat session to retrieve.
- `user_id`: (*Filter parameter*), `string`
  The optional user-defined ID passed in when creating session.

### 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:

  - `"messages"`: `list[object]`
  - `"question"`: `string`
  - `"stream"`: `boolean`
  - `"chat_id"`: `string` (optional)
  - `"session_id"`: `string` (optional)
  - `"llm_id"`: `string` (optional)
  - `"pass_all_history_messages"`: `boolean` (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?"
              }
          ]
     }'
```

##### Request Parameters

- `"messages"`: (*Body Parameter*), `list[object]`
  The latest user message, or the conversation messages sent to the model when `pass_all_history_messages` is `true`. Either `messages` or `question` is required.
- `"question"`: (*Body Parameter*), `string`
  Latest user question. This is equivalent to passing `messages: [{"role": "user", "content": question}]`.
- `"stream"`: (*Body Parameter*), `boolean`
  Enables streaming output:
  - `true`: Enable streaming (default).
  - `false`: Disable streaming.
- `"chat_id"`: (*Body Parameter*)
  Optional chat assistant ID. If omitted, the tenant's default chat model is used directly.
- `"session_id"`: (*Body Parameter*)
  Optional session ID. If `chat_id` is provided but `session_id` is omitted, a new session will be generated automatically.
- `"llm_id"`: (*Body Parameter*), `string`
  Optional model override when a specific chat model should be used for this request.
- `"pass_all_history_messages"`: (*Body Parameter*), `boolean`
  When `chat_id` and `session_id` are provided, defaults to `false`, so the server uses stored session history and only the latest user message from the request. Set to `true` to replace/use the submitted full `messages` history, and overrides the stored session history.
- `"legacy"`: (*Body Parameter*), `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`
- `"query"`: `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",
        "query": "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",
        "query": "",
        "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",
        "query": "Hello again",
        "stream": true,
        "session_id": "cb2f385cb86211efa36e0242ac120005"
     }'
```

##### Request parameters

- `"agent_id"`: (*Body parameter*), `string`, *Required*
  The ID of the associated agent.
- `"query"`: (*Body parameter*), `string`
  The question to start an AI-powered conversation.
- `"stream"`: (*Body Parameter*), `boolean`
  Indicates whether to output responses in a streaming way:
  - `true`: Enable streaming (default).
  - `false`: Disable streaming.
- `"session_id"`: (*Body Parameter*)
  The ID of the session. If it is not provided, a new session will be generated.
- `"inputs"`: (*Body parameter*), `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"`: (*Body parameter*), `array`
  File descriptors returned by the Agent file upload endpoint. RAGFlow makes the uploaded files available to the Agent through `sys.files`.
- `"user_id"`: (*Body parameter*), `string`
  The optional user-defined ID. Valid *only* when no `session_id` is provided.
- `"chat_template_kwargs"`: (*Body parameter*), `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.

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": []
        },

## 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>'
```

##### Request parameters

- `page`: (*Filter parameter*), `integer`
  Specifies the page on which the agents will be displayed. Defaults to `1`.
- `page_size`: (*Filter parameter*), `integer`
  The number of agents on each page. Defaults to `30`.
- `orderby`: (*Filter parameter*), `string`
  The attribute by which the results are sorted. Available options:
  - `create_time` (default)
  - `update_time`
- `desc`: (*Filter parameter*), `boolean`
  Indicates whether the retrieved agents should be sorted in descending order. Defaults to `true`.
- `sort`: (*Filter parameter*), `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`: (*Filter parameter*), `string`
  Fuzzy-searches agents by title.
- `canvas_category`: (*Filter parameter*), `string`
  Filters agents by one or more comma-separated canvas categories.
- `canvas_type`: (*Filter parameter*), `string`
  Filters agents by canvas type.
- `owner_ids`: (*Filter parameter*), `string`

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.

Here are the key facts:\nScientific Name: Ananas comosus\nPhysical Description: It has a tough, spiky, diamond-patterned outer skin (rind) that is usually green, yellow, or brownish. 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'
```

##### Request parameters

- `address`: (*Path parameter*), string
  The host and port of the backend service (e.g., `localhost:9380`).

---

#### 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`.

#### Request

- Method: GET

```

##### Request parameters

- `parent_id`: (*Filter parameter*), `string`
  The folder ID to list files from. If not specified, the root folder is used by default.
- `keywords`: (*Filter parameter*), `string`
  Search keyword to filter files by name.
- `page`: (*Filter parameter*), `integer`
  Specifies the page on which the files will be displayed. Defaults to `1`.
- `page_size`: (*Filter parameter*), `integer`
  The number of files on each page. Defaults to `15`.
- `orderby`: (*Filter parameter*), `string`
  The field by which files should be sorted. Available options:
  - `create_time` (default)
- `desc`: (*Filter parameter*), `boolean`

- `sort`: (*Filter parameter*), `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>'
```

##### Request parameters

- `keywords`: (*Filter parameter*), `string`
  Search keyword to filter search apps by name.
- `page`: (*Filter parameter*), `integer`
  Specifies the page number. Defaults to `1`. Values less than `1` fall back to `1`.
- `page_size`: (*Filter parameter*), `integer`
  The number of items per page. Defaults to `30`. Values less than `1` fall back to `30`. The maximum value is `100`.
- `orderby`: (*Filter parameter*), `string`
  The field to sort by. Defaults to `create_time`.
- `desc`: (*Filter parameter*), `boolean`
  Whether to sort in descending order. Defaults to `true`.
- `sort`: (*Filter parameter*), `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`: (*Filter parameter*), `string` (repeatable)
  Filter by owner tenant IDs. Can be specified multiple times: `?owner_ids=id1&owner_ids=id2`.

#### Response

Success:

```json
