We read the public page metadata — the video must be public.

How this works
YouTube embeds a hidden keywords field in every video page's metadata that never shows up in the visible UI. This tool fetches the public page source through a CORS-friendly relay and parses that field out for you. If a fetch fails, the relay may be temporarily rate-limited — try again in a moment.
