iHeartRadio is a platform for searching for and playing live radio stations and shows from both traditional radio stations and digital radio stations. Users can search for stations and shows by station, songs, and music artists.
The iHeartRadio API allows developers to access and integrate the data and functionality of iHeartRadio with other applications, and to create new applications. Full documentation is available with registration and login.
Shoutcast maintains a radio directory of 50,000+ radio stations from all around the world. The company, owned by AOL, released its first Shoutcast API a few years ago, but has since released version 2.0. The updated API provides developers with more advanced options for integrating music streaming services into web services and mobile applications using RESTful calls formatted in XML, JSON and RSS.
