How to get price of product in Drupal Commerce using Services module?

I installed Services Module and REST Server to get list of products and details. I can only get product display nodes and product id,

but how to get product price and availability info from Drupal Commerce.

List of all nodes (including product display nodes)

http://drupalcommerce.myappdemo.com/services/node

Get single product display node http://drupalcommerce.myappdemo.com/services/node/37

But it does give product id, but not product price.

Please give me an idea how to get one.

 $order = commerce_cart_order_load($uid);
   // Get the order for user just logged in.
    $order_authenticated = reset(commerce_order_load_multiple(array(), array('uid' => $this->store_customer->uid, 'status' => 'cart'), TRUE));
   //update the order status
    $form_state['order'] = commerce_order_status_update($order, 'checkout_checkout', TRUE);
    // Load the order status object for the current order.
    $order_status = commerce_order_status_load($order->status);
    $profile = commerce_customer_profile_load($order->data['profiles'][$checkout_pane['pane_id']]);
    $order = commerce_order_load($order->order_id);
   // Give other modules a chance to alter the order statuses.
    drupal_alter('commerce_order_status_info', $order_statuses);
     $order_state = commerce_order_state_load($order_status['state']);
      // Load the line items for temporary storage in the form array.
    $line_items = commerce_line_item_load_multiple($line_item_ids);
    // load line item
    commerce_line_item_load($line_item_id)
    //load the commerce product
    $product = commerce_product_load($product_id)
     // Load the referenced products.
    $products = commerce_product_load_multiple($product_ids);
