Coinbase API Python client.get_historic_prices()

I'm new to Python and API and am trying to start with some basics like making a list/plot of old BTC prices. I imported the Coinbase Wallet Client and used client.get_historic_prices(), which gave me a list of the price at midnight UTC for 365 days.

How can I adjust the parameters to get different date ranges and data resolution, for example each minute for two years? Is there a way to search the historic values of buy, sell, and spot separately?

from coinbase.wallet.client import Client 
hist_price = client.get_historic_prices()

xx=[]   
yy=[]    
for ii in range(365): 
    xx.append(ii*-1) # x coordinate being "days ago"          
    yy.append(float(hist_price['prices'][ii]['price']))

Returns (this is just from a print statement of print(hist_price['prices'][0:3]). So it's midnight once a day.

prices
length = 365
{
  "price": "974.39",
  "time": "2017-02-01T00:00:00Z"
}
{
  "price": "944.29",
  "time": "2017-01-31T00:00:00Z"
}
{
  "price": "920.47",
  "time": "2017-01-30T00:00:00Z"
}

Get_historic_prices is not clearly documented anywhere. This is a mini guide of what I have managed to discover about it and its usage. It's not much but it should be somewhere.

get_historic_prices supports one argument called period which can take the following values:

  • hour
  • day
  • week
  • month
  • year
  • all

Each of them except all returns approximately a list of 360 price points distributed more or less uniformly in the previous hour (day, week, month, year respectively).

all returns a list of price points one for each day at 00:00:00 UTC (i think).

get_historic_prices should also support a currency_pair argument as do the get_buy_price, get_sell_price, and get_spot_price do. Unfortunately, although I have submitted a PR, it has not been merged yet.
