Errors
There is a detailed guide on how to handle the ScreenshotOne API errors.
The request might return an error due to an internal error, invalid options or when the limit is reached. Our screenshot API follows the HTTP status code semantic and returns JSON in case of an error:
GET https://api.screenshotone.com/?[options]
Content-Type: application/json{ "is_successful":false, "error_code": "an_error_code", "error_message": "An error message"}The API will always return a human-readable error message, error code as a string key, and suitable HTTP status code.
