For developers using Solaris operating system and coding in Java the Bloomberg API offers this library. Solaris users should be aware that the Solaris libraries can only be used with the Bloomberg Server API and B-Pipe data feed products and are not compatible with 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 of the interface's header files, documentation, and programming examples.
TESOBE, Berlin-based software development firm, has launched the Open Bank Project with the hopes of bringing more transparency to the world's banking community. To accomplish its goal, the Open Bank Project provides an API that banks utilize to provide transaction data to interested parties. Given the hypersensitivity of financial information, the Open Bank Project must persevere through many obstacles. However, should the idea catch hold, it could be the first example of open banking as a service.
