OneMusicAPI is an aggregated API, combining several of the largest, most accurate online music databases. OneMusicAPI allows you to query all of these databases with one call. This means less integration code for you to write, debug, maintain and (re) deploy.
OneMusicAPI is lightweight; it is of a 'REST' style. You pass queries to OneMusicAPI in the form of URLs with the query details in the URL's query string. You receive results in JSON format.
