Price $0.001 per call, plus $0.001 for each extra call it makes — at most 1 more, so $0.002 in total. Only brands and rail facets add one — either makes the call 2 units. Every other filter costs nothing extra. List price; the rate steps down above 1,000 calls a day.

Parameter	Type	Required	Notes
`query`	string	yes	Keywords to search for. Required: image search and similar-item search are not available on Amazon, so a keyword query is the only way to search.
`brands`	string list		Brand names as Amazon spells them, e.g. brands=Nike,Adidas. A call that uses `brands` costs 2 units instead of 1.
`categoryId`	string		Narrow to one category, by the marketplace's own id. Opaque and per-marketplace; take it from Product.category[].id or from a result's `facets`.
`facets`	string \| object list		Narrowings taken from a result's `facets`, e.g. facets=Color:Black. A call that uses `facets` costs 2 units instead of 1.
`include`	string list		Expansions that cost more than the default answer, e.g. include=facets.
`page`	integer		1-based page number; each page is charged separately. There is no `pageSize` (Amazon fixes the count per page by keyword, 13-47 in practice) and no `cursor` — paging is by number.
`priceMax`	number ≥ 0		Highest price to return, in decimal major units.
`priceMin`	number ≥ 0		Lowest price to return, in decimal major units.
`ratingMin`	number		`4` only. Amazon's rating filter offers exactly one threshold, "4 Stars & Up"; any other value is a 400 rather than a silently different search.
`region`	string		Buyer country as ISO 3166-1 alpha-2; sets availability, shipping and price.
`sort`	enum		Result ordering: `best_match`, `price_asc`, `price_desc`, `newly_listed` or `avg_review`. Defaults to `best_match`, Amazon's own relevance ordering. `best_match` `price_asc` `price_desc` `newly_listed` `avg_review`

No pageSize. Amazon fixes the count per page by keyword — 13 to 47 in practice — with no client override, so accepting the parameter would mean ignoring it.

No cursor. Paging is by number; a cursor would be page + 1 wearing a disguise.

ratingMin is 4 or a 400. Amazon's rating filter offers exactly one threshold, "4 Stars & Up". Answering a ratingMin=3 request with 4-and-up results would be a different search than the one asked for, so it is refused instead.

brands and facets cost 2 units. Everything else costs 1. See Filters.

No condition, freeShipping or inStock.
