Yahoo finance REST api for historical stock data

Question

I can't seem to locate documentation for the following REST api (similar to):

http://finance.yahoo.com/webservice/v1/symbols/allcurrencies/quote?format=json

In my particular case I want to fetch historical stock quote data (daily stock quote for last 7 years so for a particular stock).

Answer 1

You can query for historical stocks by using yahoo.finance.historicaldata, which is an undocumented data table maintained by the community:

Try this on YQL console:

select * from yahoo.finance.historicaldata where symbol = "GOOG" and startDate = "2012-06-06" and endDate = "2013-01-01"

Be warned that since this is unofficial and not maintained by Yahoo, this query is somewhat unreliable...
