In her blog, the YouTube Team announced that it is opening its API for third-party developers.
You can watch the
video or go straight to
Google Code , where you can see the API in all its glory.
Judging by the
guide (I didn’t really read it), the API goes to the full. You can upload videos, you can manage your favorites, change ratings, add and read comments. In short, YouTube, which has already moved places with Google in the Alexa.com ranking, was not stingy. Hurray, we will wait for the mash-ups!
