Check which HTTP methods a URL supports. Test GET, HEAD, POST, PUT, DELETE, OPTIONS, and view Allow header responses. Free REST API testing tool.
The HTTP Method Support Checker on httpstatus.com probes a target URL with GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS requests and reports the status code returned for each method. It reveals whether the server responds with 405 Method Not Allowed, 501 Not Implemented, or silently succeeds, helping you map the true capabilities of an endpoint. The tool also examines the Allow response header for discrepancies between advertised and actual method support.
API developers verifying that route guards reject unintended methods, penetration testers enumerating attack surface during security assessments, and integration engineers confirming endpoint compatibility before writing client code all gain clarity from systematic method probing. Each request is sent independently, so you see the real per-method behavior without caching interference. This checker works alongside the Header Inspector and API Request Builder on httpstatus.com for thorough endpoint evaluation.
