HTTPBin — Free HTTP Request Debugging Service (No Key)

TL;DR

HTTPBin is a free HTTP request and response debugging service. Send any kind of HTTP request and get back exactly what was sent — headers, query parameters, form data, JSON body, cookies, origin IP, and more. Supports all HTTP methods (GET, POST, PUT, PATCH, DELETE) and features like auth testing, response delay simulation, status code generation, and redirect chains. Essential tool for API development and testing.

Quick start: https://httpbin.org/get

No API key needed — free HTTP debugging!

How to Use This API

1. Inspect a GET Request

See what headers, arguments, and origin IP your client sends:

https://httpbin.org/get?foo=bar&baz=qux

2. Test a POST with JSON

https://httpbin.org/post

3. Simulate a Delayed Response

https://httpbin.org/delay/5

4. JavaScript — POST JSON and Inspect Response

fetch('https://httpbin.org/post', {
  method: 'POST',
  headers: {'Content-Type': 'application/json'},
  body: JSON.stringify({name: 'Alice', role: 'developer'})
})
  .then(r => r.json())
  .then(data => {
    console.log('Headers sent:', data.headers);
    console.log('JSON sent:', data.json);
    console.log('Origin IP:', data.origin);
  });

5. Python — Test All Methods

import requests

methods = ['GET', 'POST', 'PUT', 'PATCH', 'DELETE']
for method in methods:
    resp = requests.request(method, f'https://httpbin.org/{method.lower()}')
    data = resp.json()
    print(f"{method}: {data['url']}")
    print(f"  Origin: {data['origin']}")
    print(f"  User-Agent: {data['headers']['User-Agent'][:40]}...")

6. Generate Specific HTTP Status Codes

# Test your error handling
https://httpbin.org/status/404
https://httpbin.org/status/500
https://httpbin.org/status/301

Inspect GET: https://httpbin.org/get

Frequently Asked Questions

What endpoints does HTTPBin offer?: Key endpoints: /get, /post, /put, /patch, /delete, /ip, /headers, /status/{code}, /delay/{n}, /redirect/{n}, /basic-auth/{user}/{pass}, /image, /xml, /json, and many more.
Can I test authentication schemes?: Yes — HTTPBin supports Basic Auth (/basic-auth/{user}/{pass}), Digest Auth (/digest-auth/{qop}/{user}/{pass}), Bearer token (/bearer), and Cookie-based auth testing.
How do I test file uploads?: POST to /post with multipart/form-data containing a file. The response will echo the file metadata and contents back to you.
Can I simulate response delays?: Yes — /delay/{n} waits n seconds before responding. /drip streams data over time. Useful for testing timeout handling and async behavior.
Does it support HTTPS?: Yes — use https://httpbin.org for all endpoints. HTTP also works but redirects to HTTPS.
Are there any rate limits?: HTTPBin is a free community service. It's fine for testing and debugging but not designed for production traffic. You can self-host it via the open-source GitHub repo.
