Canadian based startup LoginRadius is a Software As A Service (SAAS) provider of social infrastructure (Social Login and Social Sharing) that is currently used by over 25,000 websites. Despite being a fairly new service (The company was founded in May 2011), LoginRadius has expanded rapidly, partly in thanks to the LoginRadius API.
The US YellowPages, owned by AT&T, has revamped its developer offerings to launch a robust set of YellowPages APIs. The company also added a modern developer portal, with the ability to track API calls and test queries. The new service is part of a growing trend to share more local data via API. To kick off the new service, AT&T also launched a contest for developers.
