My Error is :

Access to fetch at 'https://cors.io/?{url}' from origin 'http://127.0.0.1:5500' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

It is third party API and I do not have access to the backend server.

My code is:

fetch('https://cors.io/?{url}',)
.then(response => {
    console.log(response);
})
.catch(err => {
    console.log(err);
});

How do I fix this problem ?

P.S. - The only work I can do is in the front end. I have no access to the backend server. Also I do not want a CORS Proxy or any third party library/code to act as proxy.
