This tool calls YouTube's official Data API directly from your browser — no data passes through Office Ultimate's servers. Your API key is saved only in this browser (localStorage) so you don't have to re-enter it every visit. Get a free key from the Google Cloud Console — enable "YouTube Data API v3" and create an API key under Credentials. The free tier covers thousands of lookups per day.
