Footfeed is a mobile geo location check-in aggregator network that lets users checkin to many networks simultaneously. The Footfeed API lets developers build multi check-in enabled applications and websites that interact with the Footfeed platform. The API can be used to create new ways to check-in to multiple services simultaneously, including Facebook Places, Google Latitude, Foursquare, Footfeed, and Gowalla or build a single check-in service app. The API uses RESTful calls and responses are formatted in XML, JSON and YAML.
