Getting the Order Placing Price

Using Kite API V3.0 to place an order.
To place the MIS Order at the Market Price, we are using following method.

// Place order.
$ord_val = $kite->placeOrder("regular", [
"tradingsymbol" => "INFY",
"exchange" => "NSE",
"quantity" => "4",
"transaction_type" => "BUY",
"order_type" => "MARKET",
"product" => "MIS",
"validity" => "DAY"
]);

$order_id = $ord_val->order_id;

Can anyone suggest how can I get the price on which order is placed.
