@sujith when u r planning to provide minute data(before Jan 2015) atleast for A-group .... Please give atleast 5 years data(from year 2011) . If u don't have it, I guess there should not be legal issue in purchasing from NSE data vendor and giving to kite member through candle API
We don't provide seconds level historical data.
You can either use websockets for live ticks or historical data API.
We don't have historical data before 2015. Buying from vendors and providing is not in our road map. We may do it in future.
I am afraid that is not possible.
