I need to find a Web Service which allows me to retrieve the following type of data:
The 30 most valuable companies, and for each company the following information:
- Company name, symbol, state and zipcode
- Current market price of the stock
- Change in the price of the stock since yesterday’s market close.
- Beta value of the stock
Thanks in advance!
I would expect to obtain this information from Forbes. As Steve suggested, you should get it from xignite.com . Apparently, Forbes makes their data available through them:

You might also have a look at Yahoo Finance: http://www.gummy-stuff.org/Yahoo-data.htm.
