This Haskell module exports functions for reading stock quotes from the Yahoo Finance APIs.

Usage

Currently, only the Yahoo Finance YQL API is implemented. They can be accessed with methods in Web.Yahoo.Finance.API.JSON. The Yahoo no longer supports the Yahoo Finance webservice so we have removed the related querying code.

λ> :set -XOverloadedStrings
λ> import Network.HTTP.Client.TLS (getGlobalManager)
λ> manager <- getGlobalManager
λ> res <- runClientM (getQuotes (YQLQuery [StockSymbol "GOOG", StockSymbol "AA"]) ) (ClientEnv manager yahooFinanceJsonBaseUrl)
λ> print res

This produces output like the following:
