Gravity, focused on personalizing the internet, has launched a new series of free APIs to further its mission. The APIs enable web publishers to recommend content to users in addition to sponsored stories from paying advertisers. Prior to the API offering, Gravity tools provided recommendations based on demographic and interests through widgets and home page personalization. The API should expand Gravity's reach into mobile apps and deeper web adoption.
