Look up ONE Coupang product by id - search-grade fields. 🔴 Read this before you call it: Coupang's product-detail page is closed to unauthenticated clients, so this action answers by asking Coupang's own search index for the id. That means you get exactly the fields a search card carries, complete and correct, and NOT a full product record. You DO get: the title, the price as a number in KRW, the list price and discount, the currency, whether it is in stock, the rating and review count, the thumbnail, the shipping terms and promised delivery date, and the item / vendor-item ids. You do NOT get: the product description, the specification table, the image gallery (one thumbnail only), the seller or vendor name, the option/variant attribute list, the stock quantity, the category path, or any review text - Coupang does not publish any of those on the surface that is open to us. 🔴 A Coupang product id covers several sellable items at DIFFERENT prices (one coffee product measured at 4 010 / 5 700 / 5 990 / 6 250 / 6 270 / 8 550 KRW for different pack sizes), so this action returns EVERY item Coupang lists under the id in `items[]` and names the one Coupang ranks first as `item` - use `items[]` if you need the cheapest or a specific pack. A dead or invented id returns NOT_FOUND rather than the recommendations Coupang backfills with.
