Technically, we have introduced some new APIs. (This is just a geeky acronym for Awesomely Powerful Interactions, which is what users are now capable of performing from just about anywhere.) Building upon our existing APIs for querying the YouTube library and playing embedded YouTube videos, we have added the following new API services for external developers and partners:
- Upload videos and video responses to YouTube
- Add/Edit user and video metadata (titles, descriptions, ratings, comments, favorites, contacts, etc)
- Fetch localized standard feeds (most viewed, top rated, etc.) for 18 international locales
- Perform custom queries optimized for 18 international locales
- Customize player UI and control video playback (pause, play, stop, etc.) through software
