The RESTful football-data.org API can be used to retrieve data on European football (soccer) leagues. The data, returned in JSON formats, includes information on fixtures (scheduled games), soccer seasons, teams, and more. The API is intended to hold accurate data, but the site states their may be lags with changes as data is not completely in real time. The football-data.org API is developed and maintained by Daniel Freitag, an independent software developer based in Germany.
