Hi @Aashish_Tahlan, you are using an incorrect instrument key. Please try using the underlying key for ICICI, which is NSE_EQ|INE090A01021.

You can use the following cURL request, and it should work:

curl -X 'GET' \
  'https://api.upstox.com/v2/option/chain?instrument_key=NSE_EQ%7CINE090A01021&expiry_date=2025-04-24' \
  -H 'accept: application/json' \
  -H 'Authorization: Bearer {auth_token}'

Thanks
