Get the full product card for one sku in this store: description, current price and stock, canonical URL, the storefront attributes the merchant filled in, and — for configurable products — the purchasable variants with their option values. Requires an exact sku, so call search_products first when only a description of the item is known. The price it returns is the one the shopper is charged. The attributes block is what this merchant maintains, not a full specification: an attribute missing from it is unrecorded in the catalog, which is not the same as the product lacking that feature. Report it as not listed rather than as absent, and never infer one from an image filename or a similar product.

Get this store's identity and policies: name, currency, locale, countries it ships to, and links to its machine-readable surfaces (llms.txt, UCP profile). Takes no arguments. Use this for questions about the merchant — where they ship, what currency prices are in — rather than about individual products.

List this store's active category tree with names, URLs and product counts, to a bounded depth. A count is the products search_products returns for that category, subcategories included where the store rolls them up. Returns id values that are the category_id argument for search_products. Use this to see what the store stocks, or to narrow a vague request before searching. Products often sit deeper than the default depth: a zero count on a category with children means look inside it, not that the store has nothing.

Search this store's product catalog by keyword, with optional category, price range, pagination and sorting. Use this when no sku is known yet. Each result is an abridged record: sku, name, type, current price, stock status, and canonical URL and image where the product has them. Prices are in the store's display currency. Results carry no attributes, no full description and no variants — the response lists what it leaves out in omitted_fields. Call get_product with a sku before stating a colour, size, material, capacity or any other characteristic of a product; a field absent from a result is absent from the result, not from the product. Put a stated category, price floor or ceiling in the matching argument rather than in query.
