The free-to-use Pokémon RESTful API (Pokéapi) is linked to an extensive database of Pokémon-related information- a true virtual Pokédex. PokeJava is a wrapper for Pokéapi constructed by GitHub contributor Mickeyjk, enabling Java applications to interface with the API. Currently on version 0.7, limited documentation is available, though the library itself should be easy to implement.
FantasyData.com, NFL statistical data provider, offers the FantasyData NFL API. The API gives developers access to NFL data (e.g. team stats, live scores, season information, box scores, and more). The API targets web and mobile app owners who develop apps for the fantasy football market. Many of the most popular fantasy football apps have already integrated with FantasyData's APIs.
Captricity, dedicated to transforming data trapped on paper into digital form, announced the public release of its API. Originally, customers accessed Captricity's technology via a web portal. In August, Captricity launched a beta API. Over the past few months, Captricity enhanced its API under the Code for America Accelerator program (one of seven startups to qualify for the honor). Captricity announced the API's public availability at Code for America's Demo Day.
