FriendFeed, the popular activity stream aggregation service have just announced their API. FriendFeed is a service that allows users to create content streams akin to the Facebook newsfeed by telling it what third-party services they use like Flickr, Twitter and del.icio.us. Friends and family can then share and subscribe to each others feeds. Given how white hot this platform is at the moment we can expect developers to jump on this API quickly. As ReadWriteWeb’s Marshall Kirkpatrick points-out this API has lots of potential and might be as popular with developers as the Twitter API, which drives them 10x more traffic than their site does.
The new FriendFeed API is REST-based and provides access to these feeds in a variety of data formats including XML, JSON, RSS and Atom. It supports a variety of read functions as well as the ability to write new links, messages, images and comments. More technical details in our new FriendFeed API profile.
Other details from the launch:
FriendFeed itself is a mashup in that they use both RSS feeds and third party APIs to aggregate the data in their streams. As time goes on we’re seeing more services that both consume the APIs of others as well as publish APIs of their own.
