YouTube Data API – Google Code


What is the YouTube Data API?

The YouTube Data API offers a simple and powerful way to access YouTube’s content in the form of Google Data API feeds. Your client application can request a list of videos that match specific search criteria, get access to the most popular YouTube videos, or get public information about YouTube users (such as playlists, subscriptions, or contacts).

The YouTube Data API is based on the Atom 1.0 and RSS 2.0 syndication formats and the Atom Publishing Protocol. Learn more about Google Data APIs.
