The Google Finance and Google Data APIs teams are pleased to announce the release of a Google Data API for the Google Finance portfolios.
This API provides easy access to user investment portfolio data, including current returns and market value. The API lets you develop applications that make it easy for your users to monitor their portfolio performance and retrieve data about the investment transactions in their Google Finance portfolio, while keeping portfolio holdings up-to-date with new transactions -- all through the same type of Google Data protocol available for Blogger, Calendar, and many other Google services. Keeping an eye on investment performance and maintaining investment holdings across multiple properties is a hassle, so we are happy to provide this API for our Google Finance portfolio users.
We're excited to see what ideas the developer community comes up with for the Google Finance Portfolios data API and hope this new feature helps you build some of the financial applications you've been thinking about. We'd love to hear your discussion!

A Google Data API arrives for Google Finance
Thursday, June 26, 2008 at 4:06 PM
Right in time for Google to be savy on storage devices and bandwith since it now looks like portfolios values will only require TINYINT fields at most :-)
Raph.
Sounds good. I have to check this out. I will be looking into the this API somewhere tonight I think... If I have time :-)
When I have something ready to show you guys I will post it on my weblog at http://johanlouwers.blogspot.com

Johan Louwers.
not sure if this is the right spot to post this.
i've written java app that does fundamental analysis on stocks. i use data from google finance to do it (the balance/income statements)
and currency info.
two problems:
1) i'm screen scraping the data - i wasn't able to find anything in the google api that would give me access to that data (4 years of data)
2) is it not possible to go farther back than 4 years? there used to be up to 6 years of data for many companies - but i think it was scaled back to four (for the sake of conistency?)
i used to use yahoo finance 100% of the time - but google finance is starting to offer more and more useful info - i think about 60% google and 40% yahoo now.
slowly getting there =)
I plan to make great use of this in flex applications at my site:

please feel free to check the stuff I create :)
thanks

When will the samples become available for .NET. I found examples for all the other APIs but not the finance. I cant even find the library for the finance API.
