Error Responses

Debugging Tips

  • Check the code and message fields for immediate clarity on the error.
  • Use the request_id when contacting support to help trace the exact call.
  • Ensure your Content-Type is set to application/json and all required fields are included.

​
Handling Rate Limits

If you receive a 429 Too Many Requests, inspect the following response headers:
HeaderDescription
X-RateLimit-LimitMax requests per minute allowed
X-RateLimit-RemainingNumber of remaining requests in current window
X-RateLimit-ResetTime (Unix epoch) when the limit resets
You should back off and retry after the reset window.

​
Retrying Safely

For paid endpoints, we recommend using Idempotency Keys to prevent duplicate billing during retries.
