DarkmindFX introduced an API that streamlines access to company financial data. DarkmindFX started with SEC-regulated companies, specifically the S&P 500. Users can easily access balance sheet and other data from companies' SEC filings. The S&P 500 is the starting point with expansion planned.
Yahoo! BOSS, the Build Your Own Search Service, has seen a series of upheavals in the last two years. When Yahoo! announced its Search partnership with Microsoft, it looked that Yahoo! BOSS might not survive for long. However, that was not the case. Yahoo! BOSS has come back strongly this year with paid version V2 and major updates to the BOSS API. In a sign that it is alive and kicking, it has announced a new home for Search BOSS and three new product offerings under the BOSS umbrella along with API updates.
Microsoft is one of the first--and certainly the largest of--customers of Wolfram Alpha's commercial API (our Wolfram|Alpha API profile). For math and nutritional searches, Microsoft's Bing now uses Wolfram results.
