ReqRes API

Beginner's Pick Development / No Auth Required Beginner HTTPS
Free to Use Varies (check documentation)

Overview

ReqRes is a free, hosted fake REST API designed for testing and prototyping front-end applications. It returns realistic user and resource data without any authentication, making it ideal for beginners learning how to work with APIs. Use it to test login flows, pagination, and CRUD operations before connecting a real backend.

Beginner Tip

ReqRes is one of the best learning tools for beginners—it supports GET, POST, PUT, PATCH, and DELETE with no setup required. Try creating a user with a POST request to see how the server returns the newly created resource with an ID.

Common Errors & Troubleshooting

404 Not Found Accessing a user ID that does not exist (e.g., /api/users/100)
Use valid user IDs (1-12). ReqRes only has a limited set of fake users.
Empty response body on POST Sending a POST without a Content-Type header
Add -H "Content-Type: application/json" and send a JSON body with -d '{"name":"test"}'.
422 Unprocessable Entity on /register Missing the password field in the registration payload
Include both email and password fields. Use one of the predefined emails like "eve.holt@reqres.in".

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
