You are here API - Libraries is a new German music sharing service similar to Soundcloud where artists can post music to connect with listeners who want to discover new music. The API allows developers to make public HTTP GET requests in order to return basic user data such as name, location, city, profile image, etc. Another type of call will return a list of the 20 most recent tracks a user has listened to, along with corresponding per-track details such as song title, description, number of likes, number of listens, and more.
