We are very excited to announce the launch of the FriendFeed API, which enables developers to interact with the FriendFeed site programmatically. It's designed to make it possible for anyone to improve FriendFeed or integrate FriendFeed into other applications. You can develop a FriendFeed interface for a mobile phone, build a FriendFeed widget for your blog, or develop an application that makes it easy to post photos to your feed from your iPhone.
If you are a non-techie, you can learn more about what the API does and how you will interact with third party FriendFeed applications by reading the FriendFeed API user FAQ.
Since the API is new, it is a work in progress, and we expect to make a number of changes in the next few months. Developers can send us feedback in the FriendFeed developer forum.
We would like to thank the folks who took the time to send us feedback on earlier versions of the API, particularly Benjamin Golub, DeWitt Clinton, Eran Hammer-Lahav, and Dave Winer. We haven't yet implemented all of their suggestions (OAuth is coming!), but we wanted to get it out to all of you for feedback in the meantime.
We are eager to see all the innovative applications people will create with the API. Happy coding!
