# YouTube APIs

> YouTube (Google) APIs provide programmatic access to YouTube data including videos, playlists, channels, user interactions, live streaming, analytics, captions, and embedded player controls. Access is over REST on Google API hosts, authenticated with OAuth 2.0 (accounts.google.com) plus API keys for public read data, and metered by a daily quota-unit system.
