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.
Yammer, a microblogging-for-business site and winner of the top prize at the recent TechCrunch50 conference, has released an API to allow developers to build their own applications around the service (Yammer API profile). Created by the people behind genealogy site Geni, Yammer has taken the tried and tested Twitter model, which asks users to answer the question "What are you doing?" in 140 characters or less, and adapted it for businesses, turning the question into "What are you working on?"
AOL is now offering developers who create applications using the Open AIM API the opportunity to make money. AIM Money is a new revenue-share platform where developers profit from ads they embed into their Open AIM applications.
This week saw the widest range of APIs being used to develop mashups we've seen in awhile: 42 different APIs used in 7 days. Of those new apps added to our mashup directory, only a handful were map mashups, whereas most of them used more unique APIs: Google Chart API, indeed API, Livekick API, MTV API, NPR API, Tagalus API, TwitPic API, uClassify API, Vimeo API, and the Yelp API. Also, given that within the last 24 hours the highly anticipated Wolfram|Alpha search engine and structured reference went live, we did happen to see a number of semantic and linked-data APIs used this week: Reuters Calais API, DBpedia API, and Freebase API (and we've just added a profile for the Wolfram|Alpha API). The list below shows which APIs were used by which mashups:
