Download Coinbase API Data via Python

Dec. 21, 2020, 5:33 p.m.by CryptoDataDownload

This is a short tutorial article that explains and gives example for how to use Python to download historical OHLC (Open, High, Low, Close) data with the Coinbase API. (*Please note that the Coinbase API is intended to be used for personal usage - refer to their market data terms). In the below Python script, we will use Pandas, requests, and json libraries to create a simple function that will ultimately write a CSV file with the filename "Coinbase_PAIR_dailydata.csv".. So if we want BTC/USD, the resulting filename will be: Coinbase_BTCUSD_dailydata.csv - Go ahead and give it a try!

This script is extremely simple, and can be greatly enhanced or fitted to meet your personal needs. It can easily be modified to save the data into a database, or pull different time frames or pairs... If you have a custom data need and would like help setting up the proper code, feel free to reach out to us

#CryptoDataDownload
# First import the libraries that we need to use
import pandas as pd
import requests
import json

def fetch_daily_data(symbol):
    pair_split = symbol.split('/')  # symbol must be in format XXX/XXX ie. BTC/EUR
    symbol = pair_split[0] + '-' + pair_split[1]
    url = f'https://api.pro.coinbase.com/products/{symbol}/candles?granularity=86400'
    response = requests.get(url)
    if response.status_code == 200:  # check to make sure the response from server is good
        data = pd.DataFrame(json.loads(response.text), columns=['unix', 'low', 'high', 'open', 'close', 'volume'])
        data['date'] = pd.to_datetime(data['unix'], unit='s')  # convert to a readable date
        data['vol_fiat'] = data['volume'] * data['close']      # multiply the BTC volume by closing price to approximate fiat volume

# if we failed to get any data, print an error...otherwise write the file
         if data is None:
             print("Did not return any data from Coinbase for this symbol")
         else:
             data.to_csv(f'Coinbase_{pair_split[0] + pair_split[1]}_dailydata.csv', index=False)
    else:
        print("Did not receieve OK response from Coinbase API")

if __name__ == "__main__":
# we set which pair we want to retrieve data for
    pair = "BTC/USD"
    fetch_daily_data(symbol=pair)
