Get Amazon product reviews

Fetch Amazon customer reviews for an ASIN. Works signed in or anonymously, and says which surface it used. With a session it reads the full /product-reviews/ list: one page of 10, with sort, star, media, reviewer and keyword filters, up to Amazon's 10-page cap. Without one it reads the product page's reviews medley instead (page 1 of top reviews, no filters, other-country reviews included), returns authenticated:false and source:product_page_medley, and throws rather than quietly ignoring a filter or page it cannot serve. Returns product (asin, title, overallRating, totalRatings, reviewCount, starBreakdown) and reviews (id, rating, title, text, date, reviewer, country, variation, helpfulVotes, verifiedPurchase, vine, images, videos). With sortBy=recent a given page is not stable across calls as new reviews arrive, so prefer sortBy=helpful for replay.

Input

asin required

10-char Amazon ASIN.

page optional

Review page to fetch (10 reviews/page; Amazon hard-caps reviews pagination at 10). One page per call — the caller loops for more. Ordering is server-controlled; with sortBy=recent the set can shift between calls as new reviews arrive, so page N is not guaranteed stable under replay (sortBy=helpful is far more stable). Pagination needs a session: an anonymous run can only read the product-page medley, which is page 1 only, and page>1 throws there.

Default: 1
sortBy optional

recent = Most recent; helpful = Top reviews. Honoured only when the run has a session; the anonymous medley serves Amazon's own top-reviews ordering regardless (check `source` in the result).

Default: "recent"
zipCode optional

US ZIP used to pin the store to the US.

Default: "10001"
mediaType optional

media_reviews_only restricts to reviews with an image or video. Needs a session, and throws on an anonymous run.

Default: "all_contents"
filterByStar optional

Star filter. positive/critical group multiple ratings. Needs a session, and throws on an anonymous run.

Default: "all_stars"
reviewerType optional

verified_reviews restricts to verified purchases (maps to Amazon's avp_only_reviews). Needs a session, and throws on an anonymous run.

Default: "all_reviews"
filterByKeyword optional

Only reviews containing this keyword. This filter returns only ratings that include a written review. Needs a session, and throws on an anonymous run.

Output

page required

Review page this result covers. Always 1 when source=product_page_medley.

source required

Which Amazon surface produced this result. reviews_page = the full /product-reviews/ list (needs a session; supports sort, filters and pagination; US store only). product_page_medley = the top-reviews block on the product page, all an anonymous browser can read: page 1 only, no filters, Amazon's own ordering, and it mixes in reviews from other Amazon stores (read `country` per review) where reviews_page returns US only. Sort/filter/pagination arguments throw on this surface rather than being silently dropped.

product required
reviews required
authenticated required

Whether the run had a usable Amazon session. False means the result came from the anonymous medley and is thinner BY DESIGN, not by failure: page 1 of top reviews only.

Search Amazon products

Search Amazon by free-text query and return one page of results. Returns query, page, zip, url, and items (asin, title, url, price, list_price, rating, review_count, image_url, sponsored). Organic results are stable per page but sponsored slots rotate between fetches; pagination caps around 20 pages.

Get Amazon product

Fetch a single Amazon product page by ASIN. Returns title, byline, brand, price, list_price, rating, review_count, rating_breakdown, availability, breadcrumb, image_url, feature_bullets, description, attributes, variant_asins, delivery_estimate, return_policy, and seller. The returned asin can differ from the requested one when Amazon resolves a variant. Price, feature_bullets, and attributes are often null or empty for books.

Get Amazon product offers from all sellers

See every seller offering an Amazon product, not just the one that won the buy box. For each offer you get the price, item condition, seller name, seller rating and rating count, where the item ships from, and the delivery estimate — enough to compare sellers on a single product. Prices, availability and delivery dates are pinned to a US ZIP code you choose, so results are consistent between runs. Products with a single seller return one offer; the buy-box winner is flagged. A seller can appear more than once when they list the same item under different conditions or shipping speeds.
