Get a CurseForge API Key

To get a CurseForge API key, visit the CurseForge for Studios website at studios.curseforge.com, then click the Login button at the top-right of the page. You will be redirected to a login page asking you to sign in with Google. At this time, signing in with Google is the only way to get an API key with this method, so you will need to use a Google account.

After you've signed in, click the "API keys" option from the left-side navigation bar. There should be an option to create an API key. This this and you will now see an API key.
