Fetch ATM , ATM+100 and ATM-100 strikes using spot

I want to place call/put option order on ATM, ATM+100 and ATM-100 strikes on NIFTY ( based on spot price ).
Is there an API available to do so? Any suggestions please?

Based on NIFTY LTP(spot price), you can calculate like below.

sample,

ATM=(Math.round(NIFTYLTP/100))*100;
ATMPlus=ATM+100;
ATMMinus=ATM-100;

TradeSymbolCE="NIFTY20JAN"+ATMPlus+"CE";
