Why is no HTTP request being made in chrome?

Question

AJAX

Hello, I am making a browser extension that also accesses a third-party api. Chrome blocks any request with the error Ensure CORS response header values ​​are valid. I googled the problem, it turns out the server just needs to send the Access-Controll-Allow-Origin header, but the problem is that I don’t have any access to the server, this is not my api. And how to be in that case? Thank you in advance!
These are the headers the server gives if you simply execute the request in the browser in a new window:

Answer 1

And how to be in that case?

Option 1: Install
CORS Unblock extension: https://chrome.google.com/webstore/detail/cors-unb...
Option 2:
Launch browser with flag: --disable-web-security (for chrome)
Option 3:
Host your own server, which will make requests to this foreign apishka and add the desired header.

Answer 2

You must give your extension permission to make cross-domain requests for specific domains.
