HTTP status codes and their meanings

HTTP status codes are 3-digit numeric codes used to indicate the status of an HTTP response from a web server. Below are some common HTTP status codes and their meanings:

Status Code	Explanation
400 Bad Request	The request format is incorrect or cannot be understood by the server. This usually indicates a client error.
401 Unauthorized	API key authentication failed. You need to verify if your API key is correct; other reasons may include token expiration.
403 Forbidden	Generally due to insufficient permissions.
404 Not Found	The requested resource was not found. You might be trying to access an endpoint that does not exist.
413 Request Entity Too Large	The request body is too large. You may need to reduce the size of your request body.
429 Too Many Requests	You have exceeded your rate limit due to frequent requests surpassing the allowed threshold.
500 Internal Server Error	An internal server error occurred. This could be an issue with the OpenAI server, not your fault.
503 Service Unavailable	The server is temporarily unavailable. This may be due to maintenance or server overload at OpenAI.
