RESTful football data. For applications of your needs.
The goal of the football-data API is to provide football data of all major european leagues in a machine-readable way. By data I mean fixtures, teams, players, results and more. All this information is provided via an easy-to-use RESTful API in JSON (only) representation.
Target audience are software developers with an affinity to football in any way and the intent of building corresponding software.
The on-site documentation should get you going quickly. I suggest you to install a JSON-View-Plugin either for Firefox or Chrome and then dive in via the Competition Resource and follow the HAL-style links of each resource to traverse the API.
If you want to implement the API seriously in a (larger) project, read the exhaustive documentation to learn the tiny details.
The API is in active development and as the current version number finally allegorizes: stable. Follow the blog for up-to-date information.
