New York Times Open announced yesterday Version 3 of the Times Newswire API. If you’re using version 2, don’t worry; that will be supported until August 2010. The Newswire API site with documentation and changes is at http://developer.nytimes.com/docs/times_newswire_api.
There’s not a huge number of changes here, but the new version does allow you to filter by sections and sources, and apparently integrates better with the Times Article Search API, though I haven’t tried that yet. The new section parameter is called section; you can either specify all or you can give specific section names; the documentation provides a URL for getting a full list of available sections. The source parameter only has three options: you can specify that you want items coming only from the New York Times, only from the International Herald Tribune, or from both papers.
While there are examples with the new parameters, I did not see any applications designed to take advantage of the newly-available parameters. However, there’s always the Times Developer Network Gallery, which shows various applications built on Times APIs. New Apps include We Read, We Tweet and Nooblast.
