Before
Access to fetch at

from origin 'https://myapp.com'
has been blocked by CORS policy:
No 'Access-Control-Allow-Origin'
header is present on the resource.
After
access-control-allow-origin: *
content-type: application/json
status: 200 OK ✓
Try It Now. No Account or API Key Needed.
Just prefix your URL and make the request.
// Instead of this (blocked by CORS):
fetch('https://jsonplaceholder.typicode.com/users/1')
// Use this:
fetch('https://corsproxy.io/?url=https://jsonplaceholder.typicode.com/users/1')
.then(response => response.json())
.then(data => console.log(data));// Cache API responses at the edge (Business plan + API key)
const url =
'https://corsproxy.io/?key=YOUR_API_KEY' +
'&ttl=900' + // Cache for 15 minutes (seconds)
'&url=https%3A%2F%2Fapi.coinmarketcap.com%2Fdata-api%2Fv3%2Fcryptocurrency%2Fdetail%3Fslug%3Dbitcoin';
fetch(url)
.then(response => response.json())
.then(data => console.log(data));
// Default caching also works with no params:
// https://corsproxy.io/?url=https%3A%2F%2Fapi.coinmarketcap.com%2Fdata-api%2Fv3%2Fcryptocurrency%2Fdetail%3Fslug%3Dbitcoin// Extract structured content (Business plan + API key)

.then(response => response.json())
.then(data => console.log(data));// Override request/response headers
