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

Usage

Currently, only the Yahoo Finance YQL API is implemented. It can be accessed with methods in Web.Yahoo.Finance.YQL.

(Note: The following usage example only works when using servant-0.9.)

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

This produces output like the following:
