The SoGeo Services API provides a set of tools to create location-based social-media applications. The API interacts with the SoGeo platform, providing access to SoGeoï¿½s database of worldwide POI, as well as deep integration with 3rd-party services such as Facebook, Gowalla, and Foursquare. SoGeo provides a platform for mobile and web, enabling businesses to create location-aware communities around their brands, products and services.
Developers can use the API to create applications for their users to explore cities and discover interesting places, track checkin/checkout behavior and popular locations, make personal maps of their favorite spots, and share their maps and spots with friends and the SoGeo community. The API uses RESTful protocol and responses are formatted in JSON.
Gowalla, Foursquare, Yelp, Facebook Places, the list goes on. There's certainly no shortage of methods to tell people where you are and what you're doing while you're there. Startup Whatser, built on the SoGeo API for location-based apps, has jumped into the ring with a different approach to check-in services: to be useful.
