The YouTube APIs and Tools let you bring the YouTube experience to your webpage, application, or device. The Data API lets you perform most of the operations a normal YouTube user can on the YouTube website. The Player APIs let you control the YouTube player using JavaScript or ActionScript. You can also use the basic embedded player, which already contains player controls, or the chromeless player, which lets you create your own player controls.
Using the SoundCloud API, you can build applications that take sound on the web to the next level. With this guide we explain and provide code examples for many common integration use cases like playing and uploading sounds or how to take advantage of SoundCloud's many social features.
