Purpose of the projectfootball-data.org provides football data and statistics (live scores, fixtures, tables, squads, lineups/subs, etc.) in a machine-readable way.
I won't announce how awesome football-data is, you're welcome to find out by yourself.
Access to the top football competitions is and will be free forever as this was the initial purpose
to setup the project.
However if you need more competitions (or in-depth data), we have several paid plans available to serve your needs.
The exhaustive documentation, code samples and libraries will help you get up and running quickly.
