The One Codex API communicates errors with standard HTTP status codes with details supplied in JSON objects. The following general pattern applies: 2XX: We received, processed, and accepted a request. 3XX: More action is required in order to complete the request. We use redirects sparingly. 4XX: Client error. Common errors relate to invalid parameters or our inability to find and serve the requested resource. 5XX: Server error. An error occurred on our system(s) while handling the request.
