Keep getting a 201 Error

I am attempting to call the Animations API using this code

And I'm getting this 201 Error

Access to fetch at 'https://api.d-id.com/animations' from origin '{my url}' 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.

Failed to load resource: net::ERR_FAILED

I implemented a retry method like some previous suggestions have said but it hasn't changed anything.

When I called the API using cURL on PowerShell it worked, but it doesn't in the browser.

Ultimately I'd like to be using the Talks API but I figured Animations would be a good place to start.

Thanks!
