Httpbin

Overview

httpbin is a HTTP request & response test service — echo your requests back, test auth headers, redirects, delays, status codes, and more. Keyless, CORS-enabled (verified live), and the de-facto tool for testing HTTP clients, proxies, and webhooks.

Quick Start

Echo the request (verified live):

curl "https://httpbin.org/get"

{
  "args": {},
  "headers": { "Accept": "*/*", "User-Agent": "curl/8.14.1" },
  "origin": "210.61.187.110",
  "url": "https://httpbin.org/get"
}

Inspect a POST:

curl -X POST "https://httpbin.org/post" -d 'hello=world'

Test a status code:

curl -o /dev/null -w '%{http_code}' "https://httpbin.org/status/418"   # I'm a teapot

Test redirects:

curl -sI "https://httpbin.org/redirect/3"

Delay / slow responses:

curl "https://httpbin.org/delay/2"

Authentication

None — keyless (/basic-auth/{user}/{pass} and /bearer help you test auth clients).

Rate Limits & Notes

• Free, no hard documented limit — be polite (it’s a public test service).
• Useful endpoints: /get, /post, /status/{code}, /redirect/{n}, /delay/{s}, /headers, /ip, /user-agent, /response-headers, /bytes/{n}.
• CORS is enabled — great for browser-side fetch tests.
• Also runs on Docker (kennethreitz/httpbin) if you need a local instance.

FAQ

Is httpbin free? Yes — free and keyless.

How do I test webhooks? Point your webhook at httpbin and use /anything or /post to capture the payload.

Can I run it locally? Yes — docker run -p 8000:8000 kennethreitz/httpbin.
