Errors
The PredictHQ API uses conventional HTTP status codes to indicate the success or failure of an API request. If you receive an error, this is what it means:
| Status Code | Description |
|---|---|
| Bad Request 400 | The request contains invalid parameters, or invalid or incomplete data. |
| Unauthorized 401 | You failed to provide an Authorization header, or your credentials are invalid or expired. |
| Payment Required 402 | Your subscription has expired. |
| Forbidden 403 | You tried to perform an action that is not authorised. E.g. you failed to request the required scope. |
| Not Found 404 | The resource or endpoint does not exist. |
| Too Many Requests 429 | You reached your global or subscription rate limit. |
| Service Unavailable 503 | The API has been switched to maintenance mode for a major or complex release. |
If you get a 404 Not Found, please check that your URL ends with a trailing slash (/).
