ReqRes

ReqRes is a hosted REST API that you can call to test HTTP clients, scripts and automated checks. It gives realistic responses from a real backend, so you can test without setting up your own server.

The public API offers stable endpoints for listing and reading users, creating, updating and deleting records, and simulating login and registration flows. Responses include the status codes you would expect from a real service, such as 200, 201, 204, 400 and 404. A delayed response endpoint helps test timeouts and loading states. An anonymous demo is rate limited per IP, and a free account gives you your own key with a higher daily allowance. The platform also lets you create your own backend with collections, auth and request logs.

• Call the demo API with no key or sign-up
• Test login, registration and CRUD endpoints
• Check responses for 200, 201, 204, 400 and 404
• Use a delayed response to test timeouts
• Build your own backend with collections and auth

QA teams, frontend developers and educators who need a reliable API to practise against will find it useful. AI agents and automated test suites can also use the stable endpoints.

A free account gives you your own API key with 250 requests a day, along with request logs and collections. The anonymous demo has a much lower daily limit and stores no data. Paid upgrades are available for larger needs, so check the plan page if you expect heavy use.
