Margin API call giving 0 even though amount is present which I can see after login

Hi zerodha team,

I am making margin call but getting 0 even though amount is present in zerodha account.

{"enabled": true, "net": 0, "available": {"adhoc_margin": 0, "cash": 0, "opening_balance": 0, "live_balance": 0, "collateral": 0, "intraday_payin": 0}, "utilised": {"debits": 0, "exposure": 0, "m2m_realised": 0, "m2m_unrealised": 0, "option_premium": 0, "payout": 0, "span": 0, "holding_sales": 0, "turnover": 0, "liquid_collateral": 0, "stock_collateral": 0}}
