import pandas as pd
import requests

def main(symbol='BTC-USDT'):
    url = f'https://api.kucoin.com/api/v1/market/candles?type=1day&symbol={symbol}'   # the API endpoint
    response = requests.get(url)  # call the API
    if response.status_code == 200:  # if result is GOOD
        data = json.loads(response.text)  # load the json response from API
        data_pd = pd.DataFrame(data['data'], columns=['unix', 'open', 'close', 'high', 'low', 'volume', 'turnover'])  # create dataframe out of json response
        data_pd['date'] = pd.to_datetime(data_pd['unix'], unit='s')  # add a human readable date
        
        pair = symbol.replace("-", "_")  # remove the - in the symbol name for the csv file
        filename = f'Kucoin_{pair}_day.csv'   # set a filename variable
        data_pd.to_csv(filename, index=False)   # write to CSV
        print(f'Wrote filename: {filename}')    # print results

    """
    This is the main portion of our script, this will call the function called main for the symbol passed to it 
    and download all the OHLCV historical data for that symbol and save the results to a CSV
