The Warner Music Group (WMG) is one of the world's largest services for recording, publishing, and global distribution of music. Their open RESTful Tour Dates API allows developers to track performance dates from WMG's artist directory. An XML or JSON response from the API will return details such as artist name(s), specific show ID, tour name, tour ID, venue name, scheduled set time, and scheduled door time. The API will also return location data on file, such as address, state, country name, zip code, timezone, and when applicable, specific longitude & latitude coordinates of venue location. Developers can filter results based on artist, country name, tour ID, tour name, or browse page per page.
