Amazon SP-API endpoint to get Billing address by order ID

I'm using Amazon Selling Partner API to import orders in my application. I'm using orders/v0/orders to get the orders list and foreach order returned I call

1. /orders/v0/orders/{orderId}/address to get shipping address
2. /orders/v0/orders/{orderId}/orderItems to get items in order
3. /orders/v0/orders/{orderId}/buyerInfo to get buyerEmail and buyerName

Now, the last thing I need is to get the eventual billing address.

I search in SP-API documentation but I didn't find anything useful.

Can someone help me?
