Costco Product API returns one product: title, description (text and HTML), feature list, specifications, rating, member-only flag, order limits, department and the item numbers of its variants. Each item carries its prices.
Take the id from the search route. Use an item number from item_numbers with the warehouse prices route. An id that does not exist in the chosen country returns 404. Costs 1 credit per successful request.
