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.
The internet is the perfect medium for matching supply with demand. You can find your next freelance job or, as Craigslist has been singled out for, find just about anything else (if you know the right euphemisms). Now, with Data Marketplace, you can request or provide datasets covering anything you can think of.
