Using a hack does run the risk of being caught and then its upto zerodha on what action they might take.
Best case scenario, they fix the hack. Worse case : they ban your trading account too.
Not saying that they will do that but why take the risk? Once you scale up they are probably one the better options for trading.
1) Fyers api is free for trading and works well.
2) IB has the best platform but they have their own limitations - good option for FnO or overnight stocks.
They also give live/historical data and platform is very stable. Minimum Rs 200 per month in brokerage or 10L in account.
