Use a Proxy Prefix
You can add a proxy prefix to the URL you're trying to access. This is similar to using a proxy server, but instead of using a separate service, you're simply adding a prefix to the URL.

const url = 'https://cors.iamnd.eu.org/?url=https://example.com/api/data'; fetch(url) .then(response => response.json()) .then(data => console.log(data)) .catch(error => console.error(error));
Use a Chrome Extension

You can then enter the URL you want to access and click the "Unblock" button. The extension will then bypass the CORS policy for you and allow you to make the request.
