Vizrt (pronounced Viz-R-Tee, short for Vizualization in Real Time), has a series of Javascript and RESTful APIs that provides access to Vizrt's Escenic Content Engine for media/broadcast organizations. The REST APIs allow developers to use the Esconic platform in PHP and .NET, among other programming languages.
Tumblr calls itself "the easiest way to share yourself" online. With Tumblr, you create "Tumblelogs," which are, essentially, online scrapbooks. Tumblr also offers an API.
