As far as I know, you can use amazon db and all contents for affiliates programs. So I and many other programs like this one, use and insert links to buy and open amazon links if you click or wish to buy them again or items like the one you'd browsed. Under fair use policy.

You can see many apps like this like: "mystuff2" or ... they'll use even Amazon name under their barcode fetch configurations.

And your other question; Yes only US Amazon implemented now, and dont have any plans for others.
