All error responses follow a consistent JSON structure to facilitate error handling and debugging.

​

Error Response Format

​

Standard Error Response

All API errors return a JSON object with a consistent structure:

{
  "error": {
    "message": "Error description",
    "code": 400
  }
}

• message: A brief description of the error
• code: HTTP status code corresponding to the error

​

Detailed Error Response (Development Mode)

In development mode, additional fields are included to aid in debugging:

{
  "error": {
    "message": "Error description",
    "code": 400,
    "detail": "Detailed error message",
    "stack": "Error stack trace"
  }
}

• detail: A more comprehensive explanation of the error
• stack: The stack trace of the error, useful for developers to trace the source of the issue

​

Common Error Codes

• 400 Bad Request: Invalid request format or missing required fields
• 401 Unauthorized: Missing API key
• 403 Forbidden: Invalid API key
• 404 Not Found: Resource not found
• 429 Too Many Requests: Rate limit exceeded
• 500 Internal Server Error: Unexpected server error

​

Error Handling Best Practices

1. Implement Proper Error Catching

   • Always wrap API calls in try-catch blocks
   • Handle both network and API errors appropriately

2. Rate Limit Handling

   • Implement exponential backoff for 429 errors
   • Monitor rate limit headers to prevent hitting limits

3. Logging and Monitoring

   • Log errors for debugging and monitoring
   • Set up alerts for critical errors
   • Track error rates and patterns

4. User Experience

   • Provide clear error messages to end users
   • Implement graceful fallbacks when possible
   • Include support contact information for critical errors
