About HTTP Status Code Reference
HTTP status codes are 3-digit numbers returned by a server in response to a client request. The first digit defines the class — 1xx informational, 2xx success, 3xx redirection, 4xx client error, 5xx server error.
How It Works
Static dataset of all standardized HTTP status codes from RFC 7231, RFC 6585, and related RFCs. No network requests. Search filters against code numbers, names, and descriptions.
