api-medic szerző: Mark Marquez

api-medic is an open-source HTTP API troubleshooting tool that adds an "api-medic" panel to Firefox DevTools. It's built for support engineers, SREs, and developers who need to quickly diagnose customer-reported API issues, but works on any HTTP request.

How it works:
Open DevTools and select the api-medic tab.
Pick a request from the Network panel.
Send it for analysis. The panel transmits that single request — wrapped as a one-entry HAR — to the hosted analyzer and renders the returned diagnostic Report inline.

What it checks:
TLS configuration and certificate issues
Redirect chains and redirect loops
Authentication and authorization headers
Content negotiation (Accept, Content-Type, charset, encoding)
Rate-limit headers (Retry-After, X-RateLimit-*, etc.)
CORS, caching, and other common HTTP misconfigurations

Privacy:
Stateless backend: no database writes, no telemetry.
Only the single request you select is transmitted, only when you click to analyze.
The hosted analyzer accepts requests only from this extension's origin.
