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 (/).
