Rated API utilizes standard HTTP response codes to communicate the outcome of an API request. It is essential to note that: * Response codes in the 2xx range signify successful execution of the request. * Response codes in the 4xx range indicate a client-side error, arising from insufficient or incorrect information provided (e.g., missing required parameters, invalid values types, etc.). * Response codes in the 5xx range signify a server-side error, indicative of an issue with Rated's servers. These are uncommon. | HTTP Code | Description | | :------------------------------------------------------------------------- | :------------------------------------------------------------------------------------------------ | | **200** Ok | Everything worked as expected. | | **400** Bad Request | The request was unacceptable, often due to a missing required parameter or an invalid value type. | | **401** Unauthorized | No valid bearer token provided. | | **403** Forbidden | The bearer token doesn't have permissions to perform the request. | | **404** Not Found | The requested resource doesn't exist. | | **429** Too Many Requests | The number of requests to the Rated API is too high. Back-off and try again later. | | **500, 502, 503** Server Errors | Something failed on our servers. |
