🆘 Troubleshooting

Connection Issues

"Network error - check your internet connection"

• Cause: CORS restrictions when opening index.html directly
• Solution: Use the local web server instead:

  python start_server.py
  # Then open http://localhost:8000

"Invalid API key - check your Claude API key"

• Verify your API key starts with sk-ant-
• Get a new key from console.anthropic.com
• Ensure no extra spaces or characters

"API access forbidden"

• Check your Anthropic account has API access enabled
• Verify your account has sufficient credits
• Check for any account restrictions

Camera Issues

Camera access denied

• Grant camera permissions in your browser
• Check browser security settings
• Ensure you're using HTTPS or localhost

Frame capture not working

• Refresh the page and try again
• Check browser compatibility (Chrome/Firefox recommended)
• Verify camera is not being used by another application

🆘 Support

For additional issues or questions:

1. Check the browser console for detailed error messages
2. Verify Claude API key and connection using the test button
3. Try running from a local web server instead of opening the file directly
4. Review input format requirements
5. Check the console for setup instructions
