=head1 NAME

Finance::GDAX::API::Quote - Get a quote from the GDAX

=head1 SYNOPSIS

  use Finanace::GDAX::API::Quote;
  my $quote = Finance::GDAX::API::Quote->new(product => 'BTC-USD')->get;
  say $$quote{price};
  say $$quote{bid};
  say $$quote{ask};

=head1 DESCRIPTION

Gets a quote from the GDAX for the specified "product". These quotes
do not require GDAX API keys, but they suggesting keeping traffic low.

More detailed information can be retrieve about products and history
using API keys with other classes like Finance::GDAX::API::Product

Currently, the supported products are:

  BTC-USD
  BTC-GBP
  BTC-EUR
  ETH-BTC
  ETH-USD
  LTC-BTC

  ETH-EUR

These are not hard-coded, but the default is BTC-USD, so if any are
added by GDAX in the future, it should work find if you can find the
product code.

  size
  bid
  ask
  volume
  time
