How can we get the list of instrument keys for all FnO stocks

Hi @RAVI_5894658
You can obtain the list of instrument keys for all FnO stocks from the instrument JSON file available at this link. To filter the data, use the instrument_type field, which can have the values FUT, CE, or PE.

I hope this addresses your query.

Thanks!

This doesn’t adrress our query, still can find the instrument_key for the stocks, “FOR THE STOCKS individual stocks” that are also in FnO.
this filters out the json file and provde json file of 69000 line while i need instrument key for 215 stocks only

To retrieve the required data, first, identify the instrument key for the stock. Once you have the instrument key, apply a filter using underlying_key, exchange, and segment as NSE FO. You can also use the underlying_symbol of the stock.

For reference, see the example contract for Reliance:

{
    "weekly": false,
    "segment": "NSE_FO",
    "name": "RELIANCE INDUSTRIES LTD",
    "exchange": "NSE",
    "expiry": 1743100199000,
    "instrument_type": "CE",
    "asset_symbol": "RELIANCE",
    "underlying_symbol": "RELIANCE",
    "instrument_key": "NSE_FO|141321",
    "lot_size": 500,
    "freeze_quantity": 20000.0,
    "exchange_token": "141321",
    "minimum_lot": 500,
    "asset_key": "NSE_EQ|INE002A01018",
    "underlying_key": "NSE_EQ|INE002A01018",
    "tick_size": 5.0,
    "asset_type": "EQUITY",
    "underlying_type": "EQUITY",
    "trading_symbol": "RELIANCE 1070 CE 27 MAR 25",
    "strike_price": 1070.0,
    "qty_multiplier": 1.0
}
