I understand how to trade crypto with the Krakenex API using something like the following

import krakenex

def main():
    kraken = krakenex.API()
    kraken.load_key('kraken.key')

    response = kraken.query_private('AddOrder',
                                    {'pair': 'XXBTZEUR',
                                     'type': 'buy',
                                     'ordertype': 'market',
                                     'volume': '0.001'
                                     })
    return response

if __name__ == '__main__':
    ret = main()
    print(ret)

However if I were to plug my futures trading api key in rather than my spot api key it will give me “{'error': ['EAPI:Invalid key']}“.

I have already tried to achieve this effect by simply swapping the spot key for the futures key and I am trying to do something similar to the code provided earlier but with futures.
