This C++ library for Windows interfaces with the Bloomberg 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. Extensive documentation, including code examples, is available in the Developer Documentation and at the API website.
Bitcoin's explosive growth in APIs--45 so far in our directory--owes its pace to three cornerstone APIs that make possible a new form of trust, trust by computation rather than the old financial trust built on exclusion.
Have you ever wanted to own your very own API, but did not have the time or inspiration to create one for yourself? Well here is your opportunity. Song.ly, a Twitter music sharing service, is up for grabs.
