Binance API CORS

Fix Binance API CORS errors

Crypto dashboards often need public API data directly in the browser, but exchange APIs may not send CORS headers for your origin.

Use in Production Try in Development

One prefix

  .then(response => response.json())
  .then(data => console.log(data));

When this helps

Free for development, paid for production

Production adds higher throughput, allowed domains, and request analytics so live crypto tools are easier to operate.

Production domains need an API key. Free stays focused on localhost-like development so the production path stays reliable.
