# or more something like
client = Avantage::Client.new(File.read('.api.key').strip)Functions may be called directly:
require 'pp'
pp client.get(:global_quote, symbol: 'GOOG')
#
# ==>
#
# {"Global Quote"=>
# {"01. symbol"=>"GOOG",
# "02. open"=>"1109.6900",
# "03. high"=>"1116.3900",
# "04. low"=>"1098.9995",
