YouTube API quota increases require privacy policy and ToS updates referencing YouTube API Services, even for internal-only usage.
Increasing the YouTube Data API search.list per-method quota beyond the default 100/day requires submitting a compliance audit form through Google Cloud Console. The form requires:
youtube.search.list, youtube.channels.list, youtube.videos.list, youtube.playlistItems.list).This applies even for purely internal/server-side usage with no end-user-facing YouTube integration. The API itself is free — quotas are rate limits, not billing caps. The overall 10,000 units/day limit is separate from per-method limits (search costs 100 units each; channels/videos cost 1 unit each).
