Resolve an Amazon ASIN to its global trade item numbers. The response echoes the asin and returns a results array of value / type pairs — UPC, EAN-13, or ISBN depending on the product. A single ASIN can map to multiple codes, and the country parameter resolves against the right marketplace catalog.
