HTTP Status Codes and Their Meanings

HTTP status codes are 3-digit numeric codes used to represent the HTTP response status of a web server. The following are some common HTTP status codes and their meanings:

Status Code	Code Explanation
400 Bad Request	The request format is incorrect or cannot be understood by the server. Usually means a client error.
401 Unauthorized	API key verification failed. You need to verify whether your API key is correct. Other reasons include token expiration.
403 Forbidden	Generally insufficient permissions.
404 Not Found	The requested resource was not found. You may be trying to access a non-existent endpoint.
413 Request Entity Too Large	The request body is too large. You may need to reduce your request body size.
429 Too Many Requests	You have exceeded your rate limit due to frequent requests.
500 Internal Server Error	Internal server error. This may be an OpenAI server issue, not your problem.
503 Service Unavailable	The server is temporarily unavailable. This may be due to OpenAI undergoing maintenance or server overload.

Note: The above are only some HTTP status codes, not all. Some status codes may vary depending on the server's implementation and usage.
