Httpbin Verified Jul 2026
Httpbin.org is Kenneth Reitz's classic HTTP testing service — hit any of its endpoints (/get, /post, /headers, /status/<code>, /delay/<n>, and more) and it echoes back exactly what your client sent, making it a staple for debugging request/response behavior, auth headers, redirects, and streaming. It needs no key and returns JSON by default, with dedicated endpoints for HTML, XML, and binary payloads too. Now maintained by Postman under the postmanlabs org, the service is known for intermittent outages under load — this session hit repeated 503s from its AWS load balancer before it recovered — so momentary unavailability is a known quirk, not a sign the service is gone.
