Check out the OIPA: Openaid IATI API.
League of Legends
League Of Legends Api so developers can easier access in game data and use in their own sites. There is no real open api by Riot yet, so I thought I would see if there is any interest in using mine until there is an official one! :) http://legendaryapi.com Update: http://ddragon.leagueoflegends.com/tool/euw/en_US
