Historical API syntax

Dear developing team, kindly publish the examples for the available python APIs. we are having very difficult time figuring out the syntax.

I was trying to access the historical API. I have used the below syntax and none of them are working for me.

kite.historical("408065","2017-12-13 09:15:00","2017-12-13 9:30:00","1minute","0")

the error i'm getting is
in historical "continuous": 1 if continuous else 0
TokenException: Invalid API credentials

so I can make out that the last parameter I'm passing is not correct. I have tried all possible things but no luck yet.

have tried below syntaxes

kite.historical("408065","2017-12-13 09:15:00","2017-12-13 9:30:00","1minute",0)
kite.historical("408065","2017-12-13 09:15:00","2017-12-13 9:30:00","1minute","continuous=0")

can't make out what to be passed.
