Single purpose API
JSON, JSONP, REST
Stack Exchange, the community driven Q&A site network, has been a favorite with developers due to its high quality content. The Stack Exchange API, which was first released in mid-2010, has seen a good adoption by developers and several quality applications using the API are listed here, in typical Stack Overflow answer style. The company is bringing its new API into beta and ushering it in with a contest.
APIs are now the cornerstone of most product offerings. Early API Providers are now at a stage where their early API offerings have been truly tested by developers. In their quest to fine tune their API, these organizations have mined through usage patterns, API bottlenecks and many more parameters to help understand what they could have done different if given a chance (read that as version 2.0). Kevin Montrose of Stack Exchange, one of the most popular collections of Q&A sites, has published a couple of blog posts on the good and bad parts about the Stack Exchange API, that provides a good lesson to all of us.
Stack Exchange, the network of community-driven Q&A sites, held a developer contest recently for their API. Developers were invited to write applications that work with Stack Overflow, Server Fault, Super User and Meta Stack Overflow. Among the winners were an iPhone application, a printable view and a web widget.
