 For per-entry subaccount routing, build the request explicitly:
 
 ```python
 from kalshi import BatchCancelOrdersRequestOrder
 
-client.orders.batch_cancel([
+result = client.orders.batch_cancel([
     BatchCancelOrdersRequestOrder(order_id="ord_abc", subaccount=0),
     BatchCancelOrdersRequestOrder(order_id="ord_def", subaccount=1),
 ])
