Request to enable CORS

[mriot]

Hi,
First off, thanks for your API—much appreciated!

I'm working on integrating it into a browser extension and noticed CORS is currently blocked:

Access to fetch at 'https://favicone/' from origin 'chrome-extension://xyz' has been blocked
by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Is there any chance CORS support could be enabled?

Btw I'll gladly open a PR to get my extension listed once it's published!
