CORS Proxy Service

This service allows you to bypass CORS issues for your API calls.

2. How to Use

A) For Deployed Applications (Live Environment)

When your app is live on your registered domain, include the X-User-Email header with your registered email in your fetch request.

const target = encodeURIComponent('https://api.example.com/data');
const workerUrl = `https://cors.utilitykit.workers.dev//?corsUrl=${target}`;

fetch(workerUrl, {
method: 'GET', // Or 'POST', etc.
headers: {
  // REQUIRED: Your registered email
  'X-User-Email': 'you@example.com'
}
})
.then(res => res.json())
.then(data => console.log(data));

B) For Local Development (localhost)

When you register, you will receive a Development Token. Use this token in the X-Dev-Token header to make requests from localhost.

const target = encodeURIComponent('https://api.example.com/data');
const workerUrl = `https://cors.utilitykit.workers.dev/?corsUrl=${target}`;

fetch(workerUrl, {
method: 'GET',
headers: {
  // REQUIRED: Your unique development token
  'X-Dev-Token': 'YOUR_DEV_TOKEN_HERE'
}
})
.then(res => res.json())
.then(data => console.log(data));
