CORS Proxy

API

Free proxy API to bypass CORS restrictions easily

Overview

A RESTful proxy API designed to help developers resolve cross-origin resource sharing (CORS) errors. It acts as an intermediary, accepting target URLs via query parameters (e.g., `/proxy?url=https://example.com`) and forwarding GET/POST/PUT/DELETE requests. Responses retain the original format (JSON, XML, text) from the target while adding necessary CORS headers. Ideal for testing local frontend apps against remote APIs without CORS support, debugging cross-origin issues, or enabling client-side access to restricted services.

Example Integration (JavaScript)

script.js JS


fetch('https://github.com/burhanuday/cors-proxy')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
