67 Database Records
The HTTP Protocol Error Codes List provides a current structured reference to numeric entries in the authoritative IANA HTTP Status Code Registry. Each record includes the code, response class, IANA description, registration status, and defining reference. Standard registered codes are clearly separated from temporary, unused, and obsoleted registry entries. Unassigned ranges and nonstandard vendor or framework codes are excluded. The free protected package includes matching UTF-8 CSV, JSON, and SQLite files plus schema, sample, statistics, licensing, and signed release evidence.
