If you're looking for a free API for testing, you usually want one thing: something you can hit immediately without setting up a backend, database, or authentication system.
ReqRes provides a public REST API that developers and QA teams use every day to test HTTP clients, frontend apps, and automation scripts.
Below are real examples you can use right now.
Basic GET request
curl https://reqres.in/api/users?page=2
This returns realistic JSON data with pagination, making it ideal for smoke tests and quick validation.
Creating data with POST
curl -X POST https://reqres.in/api/users \
-H "Content-Type: application/json" \
-d '{ "name": "Jane", "job": "QA Engineer" }'
You'll receive a structured response and status code similar to a real backend.
Why teams use ReqRes for testing
Teams use ReqRes because it:
- Requires no setup or credentials
- Returns predictable, realistic responses
- Works with Postman, curl, Playwright, Cypress, and REST clients
When a free API isn't enough
If you need persistent data, per-user isolation, or authentication flows, ReqRes Projects lets you turn the same patterns into a real backend without standing up servers.
