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.

Your endpoint format looks correct, but the issue may be related to the available historical data or the time range returned by the KuCoin candles endpoint. Try specifying startAt and endAt as Unix timestamps, and also confirm that BTC-USDT is the exact currently supported symbol for the API version you are using. For example: /api/v1/market/candles?symbol=BTC-USDT&type=1hour&startAt=...&endAt=... If the request succeeds but returns an empty data array, checking the current KuCoin API documentation is worthwhile, as the endpoint and supported market symbols may have changed since this question was originally posted.
