ReqRes

API

Hosted REST API for testing AJAX requests

Overview

ReqRes offers a set of hosted REST endpoints (e.g., /api/users, /api/login, /api/register) designed for testing frontend applications and AJAX interactions. Responses are in JSON format, supporting standard HTTP methods (GET, POST, PUT, DELETE). It’s ideal for developers practicing API integration, mocking user authentication flows, or simulating data fetching without building a backend. Features include pagination, filtering, and error scenarios (like invalid login) to replicate real-world API behavior.

Example Integration (JavaScript)

script.js JS


fetch('https://reqres.in/')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
