I need to access kucoin Open-high-low-close (OHLC) data from Kucoin API.

Looking in https://docs.kucoin.com/#get-trade-histories, I deduced that to access OHLC data (for instance BTC versus USDT, with hourly timestamp), the address should be something like this :

https://api.kucoin.com/api/v1/market/candles?symbol=BTC-USDT&type=1hour

Doing that, I get empty list for the data {'code': '200000', 'data': []} (according to kucoin API doc, code 200000 correspond to a good request)

What I am doing wrong ?

ps : same method worked very well on kraken api (e.g. https://api.kraken.com/0/public/OHLC?pair=xbtusd )

ps2: this question was originally asked on https://stackoverflow.com/questions/56572249/how-to-access-kucoin-ohlc-data-from-api but with no response for the moment. Perhaps this bitcoin stackexchange is better adapted.

Thank you very much in advance for your help !

To obtain the information you seek:
I use the a variable called kline and a json formatted request.
It looks like this:

kline = requests.get(url + '/api/v1/market/candles?type=1min&symbol=
                     '+Cry+'&startAt=1566703297&endAt=1566789757')
# Then I convert it to json
kline = kline.json()
# turn that into a dataframe where I pull the data dictionary
kline = pd.DataFrame(kline['data'])
# Then I rename the columbs as so
kline = kline.rename({0:"Time",1:"Open",
                2:"Close",3:"High",4:"Low",5:"Amount",6:"Volume"}, axis='columns')
# Set the index as time
kline.set_index('Time', inplace=True)
# To assist I will call the head and and print for you
kline.head()
print(kline)

As you should know, once you have it as a dataframe you can manipulate it as you please.
