From their site: The Digg Application Programming Interface (API) has been created to let users and partners interact programmatically with Digg. Digg is a place for people to discover and share content from anywhere on the web. From the largest sties to the smallest blogs, Digg surfaces the best stuff as voted on by users. The API returns Digg data in a form that can be integrated into an application or a web site. The API is available to everyone free of charge, but its use is subject to acceptance of the API License Agreement.
Many APIs eventually find their way to the ProgrammableWeb deadpool. They end up there for various reasons: no business model, replaced by a newer service or ceased being useful. The most popular of these dead APIs are predominantly from two big tech firms: Google and Yahoo. Search and mapping make up the bulk of the functionality behind these 12 popular--but no longer available--APIs.
Developers looking to create applications any kind of news content, including breaking news, crowdsourced news, business news, local news, sports, politics, market updates, and more, should look no further than ProgrammableWeb's directory. The API Directory includes 81+ news APIS.
When Facebook announced its timeline partners yesterday, there were many familiar names on the list. Some were especially familiar to us because, in addition to now adding their "actions" to Facebook, they also provide APIs to access data created by their users.
