Football Data API is operated by the team at footystats.org. The team consists of seasoned web entrepreneurs who are avid football fans as well. We dabble in predictions every one and then. The database is maintained daily ~ weekly, with new features and data points being added on a regular basis. Requests are welcome at firstname.lastname@example.org
