OI data is zero


I am trying to get open interest data from tick in websocket client for NIFTY option (Example : NIFTY21N1818100CE).
I am getting zero when I use tick.getOi(). It is tried when market is open.
Is there any API which gives total number of OIs in CALL/PUT side.

    def on_ticks(ws.ticks):
    for tick in ticks:
