A couple of weeks ago on Twitter, I asked about freely available financial data.
Anyone know where to get stock data in a standard API format (XML, JSON, etc)? Just looking for hi/lo/close data, not real-time.
I may or may not get around to doing the project I wanted the data for, but in the meantime, here's a list of the suggested resources that people sent in:
- Google Finance's CSV output (example)
- Google Finance API for gadgets.
- Yahoo Finance's CSV output (example)
- There's a stock quote example in this IBM article on using YQL, JSONP, and jQuery.
- The Stock Quote web service from WebserviceX.net.
- Data from Infochimps: AMEX, NASDAQ, NYSE.
Update: Getting stock information with YQL. (via @jonathantrevor)
