With check_inventory, a cart check that cannot read a quantity is retried once on another session; one that still fails says so on the offer, inventory_response {\"error\": \"cart check failed\", \"code\": \"cart_check_failed\", \"retryable\": true}, is not billed, and never reads as a quantity of 0. Each offer carries `ships_from` (the \"Ships from\" name: Amazon for FBA, else the seller), `delivery_message` (the offer's own delivery promise, e.g. \"FREE delivery Friday, October 16 on orders shipped by Amazon over $35\") and `delivery_message_secondary` (the \"Or fastest delivery ...\" line), null when the offer shows none. `delivery` is the same value as `ships_from`, kept for existing integrations; it never held delivery information. A row for an ASIN that could not be answered carries `error`, `code`, `http_status`, `billed`, `retryable` and `next_step`, like a top-level error: `upstream_unavailable` (not billed, retry that ASIN), `no_offers` (\"No offers found\": the offer list holds no offer that can be bought as is -- customizable listings have none; billed like a 404) or `asin_redirected` (Amazon answers the ASIN with another listing's offers; billed like a 404). On agent.apiguru.app the answer also carries `success` and `_links` (self, and `details_url` per row); `billable_requests_count` is there on your own key only.",

Fetches the complete product record for one ASIN on one marketplace: title, price, star rating, rating count, images, description, feature bullets, variations and category.

Every answer carries filters_applied, filters_ignored (with the reason) and available_filters for that marketplace. Price: $0.003 per call. Blank values and the literal string 'null' are treated as unset. Invalid page, sort_by, price, product_condition or deal_type is a free 400 naming the parameter and the allowed values. Condition and deal refinements are per marketplace; a marketplace that lacks one gets the unfiltered feed plus an entry under filters_ignored, never a silent empty page. `product_num_ratings` and `offers_count` are integers; `product_star_rating`, `product_price` and `product_original_price` are decimal strings; a null field means Amazon did not show it. `is_prime` is true when the result carries a Prime badge or its delivery line offers Prime delivery. `metadata.total_pages` says how far `page` can go. A full page is up to 48 results and about 54 KB; the tool returns the first 10 as light rows by default and the answer carries `_truncated`, `_omitted_fields`, `_projection` and `_notes`. filters_applied echoes the effective sort_by (RELEVANCE when none was sent). A BEST_SELLERS ordering is Amazon's query-scoped popularity, not a category rank: a row's `badges` / `is_best_seller` are what the result card showed for this query, and an ASIN that is #1 in its subcategory can carry no badge here while product_details reports best_seller=true with the rank. For a rank claim, use product_details or best_sellers. An empty `products` list is served as success only when Amazon itself reports 0 results (metadata.total is 0 and `hint` says so).

Price: $0.003 per call. A malformed seller_id is a free 400, as on seller_profile_batch. metadata.total_pages counts every page of the result (48 rows a page), but Amazon serves at most 7 pages of one query: metadata.reachable_pages is how far page can go, and when it is less, pagination_note says how to see the rest (min_price/max_price bands or category_id). _links.next is the next page while there is one; a page past the end is a free 400 page_out_of_range. Invalid sort_by, price, product_condition or deal_type is a free 400 that lists the allowed values. No single sort order lists a whole storefront: Amazon's relevance order (the default) can count far fewer products than the store holds and repeats products across pages, and other orders include products it leaves out (measured on one store: relevance 321, NEWEST 1,898; on another, relevance and NEWEST shared 90 of 161 products). Page 1 of a storefront without `query` carries `coverage_note` with the recipe: page through sort_by=RELEVANCE and sort_by=NEWEST, split a store larger than 336 products into min_price/max_price bands, dedupe by asin. An empty storefront carries `note`: Amazon reports 0 products for a seller with no listings on that marketplace and for an id that is not a seller alike, so check it with seller_profile_batch (`_links.seller_profile`). Rows have the search row shape: `offers_count` is null unless the card shows a count, and `product_brand` is null on most storefront cards (Amazon prints no brand line there; product_details has `brand_name`).",
