For developers using OS X and Perl, the Bloomberg API offers this library. OSX users should also note that the OSX libraries are only compatible with OSX 10.7 and later, and can only be used with the Bloomberg Server API and B-Pipe data feed products (not the Desktop API). The Bloomberg API provides free, unrestricted access to raw financial data on current market trades (either real-time or delayed), reference data on historical information, and records of intraday trading. As part of their Open Market Data Initiative the library is offered under a "free-use" license, which allows unrestricted access to the interface's header files, documentation, and programming examples.

YPG understands the YellowAPI is a natural extension of its existing business model, and extends the reach of its advertisers by feeding their listings through 3rd parties applications built on the platform.
