I'm looking for access to financial data from Google services.
I found this URL that gets the stock data for Microsoft.
What are all the possible parameters that Google allows for this kind of HTTP request? I'd like to see all the different information that I could get.
There's a whole API for managing portfolios. *Link removed. Google no longer provides a developer API for this.
Getting stock quotes is a little harder. I found one article where someone got stock quotes using Google Spreadsheets.
You can also use the gadgets but I guess that's not what you're after.
The API you mention is interesting but doesn't seem to be documented (as far as I've been able to find anyway).
Here is some information on historical prices, just for reference sake.
You can also get charts: https://www.google.com/finance/getchart?q=YELP
Note that if your application is for public consumption, using the Google Finance API is against Google's terms of service.
