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!
