Yahoo
Developer Platform
Yahoo! Developer Network is Yahoo!'s site for developers, where it offers free access to its collection of web services, in addition to multiple software development resources. YDN offers Web Services and APIs to make it easy for developers to build applications and mashups.
We developed tools used by Yahoo! worldwide, as well as launched several Yahoo! properties from scratch. We also helped to drive the internal Yahoo! APIs out into the world as REST APIs before most people knew what REST was.
