Getting stock quote for a single symbol

{:ok, quotes} = YahooFinanza.Quote.fetch(["AAPL"]) ## => {:ok, [%{"Symbol" => "AAPL", ... }]}

It's properties can be accessed like so:

quote = quotes |> List.first
quote["Ask"] ## => 12.0

{:ok, quotes} = YahooFinanza.Quote.fetch(["AAPL", "FB"]) ## => {:ok, [%{"Symbol" => "AAPL", ... }, %{"Symbol" => "FB", ... }]}
