Popular "hyperlocal" news and information service Outside.in recently released an API (our Outside.in API Profile) that provides developers with a way to access up-to-the-minute, location-based news. Based on its “news around you” feature, Radar, the API provides access to various types of information, including the latest news stories, blog posts, Twitter tweets and more located within 1,000 feet of a specific location.
Ten APIs have been added to the ProgrammableWeb directory today in categories such as Location, Events, Marketplace, and Travel. We have highlighted the APIs here, including four more APIs from TipsGo, which helps developers make accurate money management mobile applications.
