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. This library allows OSX users to develop their API in Java. As part of their Open Market Data Initiative Bloomberg API libraries are offered under a "free-use" license, which allows unrestricted access to the interface's header files, documentation, and programming examples. Users should 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).
Moving money online is commonplace these days, and the simpler and faster the process can be, the more appealing it is. Ripple provides another option in the world of online payment solutions. It's an open source, almost free to use payment network that provides a simple and hassle-free way for anyone in the world to send money to anyone else. The Ripple API allows developers to use this functionality and integrate the payment system into other projects.
ValueAppeal is a service to help U.S. homeowners appeal the assessed value of their home. Over-assessed property results in taxes that are higher than they should be. This means that homeowners may be over-paying their taxes by anywhere from $500 to $1,000 or more. I wouldn’t mind keeping an extra $1,000 of my money per year going forward and I bet the same goes for most of America. If you have a website focused on real estate (did anyone mention this to Zillow?) the ValueAppeal API could augment it with compelling information.
