API and Auth Debugging Tools for JWT, Headers, and HTTP Statuses
API debugging depends on seeing the important pieces immediately: headers, tokens, params, and status meanings. This category keeps that context visible and scannable without sending data to a server.
- JWT inspection with expiry awareness
- HTTP status lookup and response guidance
- Header and query parsing for raw request debugging
