I'm using instrumental data from the api but the price is always coming to be 0 rs nothing changing
Are you trying to fetch the last price data from the complete instrument list? If yes, then a complete instrument list is used to get instrument token detail, not for last_price data. For Quote data, you can use any of the Quote APIs.
