The API uses standard HTTP status codes to indicate the success or failure of an API call.

  • 400 (Bad Request) The server could not process the request, most likely because of an invalid argument.

  • 401 (Unauthorized) Your request lacks valid authentication credentials, your API key is missing in the request headers.

  • 402 (Payment Required) Your API request was rejected due to it being a paid subscription plan with an overdue balance.

  • 403 (Forbidden) Your request was rejected due to a permission issue, likely a restriction on the API Key's associated service plan.

  • 429 (Too Many Requests) The API Key's rate limit was exceeded.

  • 500 (Internal Server Error) An unexpected server issue was encountered.
