PAAPI see if item is eligible for free international shipping

Is there a resource or variation that I could add to a PAAPI (Product Advertising API) request to filter/sort for items that are eligible to ship free internationally: https://www.amazon.com/gp/help/customer/display.html?nodeId=GY48Z9B62JLTAQV2

Such as here, if there could be an additional DeliveryFlag for Free Global/International Shipping: https://webservices.amazon.com/paapi5/documentation/search-items.html#deliveryflags-parameter

I'm asking here because the API Discussion Forum says it was moved to re:Post
