We have covered the BigML API before because of its innovative use of machine learning through an API tied up with very easy to use interface. Think of it as Google Prediction API but without a black box algorithm, and with enhanced real time data visualizations and a much better user interface and crisper documentation.
Informatica is looking to make the lives of developers simpler on two fundamental planes of existence. The first is allowing developers to leverage Informatica APIs to create their own connectors.

As a developer, you can figure out how to make your program connect to Facebook, Twitter, SMS, and Email. Or you can use the Embarke API and connect just to Embarke, a messaging platform that connects you to them all. You can skip learning the specifics of how to connect to each of them. The REST API's website has a five minute tutorial video on how to use this gateway to its developer tools for social communications.
