In a well-received move, major British newspaper The Guardian has opened up access to its content and data sets to third parties. The Guardian's Open Platform comprises both an API (our new Guardian API Profile) and a Data Store that provide access to multimedia content and data sets respectively. The Content API includes approximately 1,000,000 articles that go as far back as 1999 and in some cases much further back.
Our API directory now includes 453 search APIs. The newest is the Automatton Instant Answers API. The most popular, in terms of mashups, is the eBay API. We list 220 eBay mashups. Below you'll find some more stats from the directory, including the entire list of search APIs.
