title: Historical ethereum prices - Coinbase API
body: <p>Using the python coinbase API-- The functions-- <code>get_buy_price</code>, <code>get_sell_price</code>, <code>get_spot_price</code>, <code>get_historical_data</code>, etc... all seem to return bitcoin prices only. Is there a way of querying Ethereum prices? </p>
  
  <p>It would seem that <code>currency_pair = 'BTC-USD'</code> could be changed to something akin to <code>currency_pair = 'ETH-USD'</code> although this has no effect.</p>
  
  <p>I would expect that the API simply doesn't support this, except that the official documentation explicitly states: </p>
  
  <blockquote>
    <p>Get the total price to buy one bitcoin or ether </p>
  </blockquote>
  
  <p>I can work around this somewhat by using the <code>quote='true'</code> flag in the buy/sell request. This however only works moving forward, I would like historical data.</p>
