Quova's is a geolocation service, went free last November. The company has revamped its developer portal and added a few awesome new features to the Quova API. The company also added JSON as a response format, as so many other APIs have lately. Unlike the APIs ditching XML, Quova is keeping the XML format and expanding developer options. Also, the company added a developer forum and app gallery to its portal, to encourage community around its API.
