$2.00 / 1K · pay per delivered review

An Amazon reviews API that takes an ASIN or product URL and returns customer reviews as rows: star rating, title and full text, review date and country, the Verified Purchase and Vine flags, helpful votes, the purchased variant and any review images. Works across Amazon marketplaces with top/recent sorting and star filters, priced per delivered review.

What it does

What an Amazon reviews API does

Reviews are the only part of a product page written by customers, and the flags around them decide what a row is worth: a Verified Purchase five-star and an unverified one are different signals, a Vine review is a third thing, and helpful votes rank the text the crowd found true. All of that arrives as columns, with the purchased variant attached — so "runs small" can be tied to the size that runs small.

One run reads the reviews published on the product page — typically 8 to 13 — and delivers at most 20.

Inputs

The whole request. Anything you leave out falls back to the default shown in the catalog.

Input	Type	Required	What it does
`product`	string	yes	ASIN (10 characters) or Amazon product URL.
`country`	string	no	ISO 3166-1 alpha-2 code — picks the local site AND the proxy exit (default us).
`sort`	string	no	Review order (default helpful). One of: `helpful`, `recent`.
`stars`	string	no	Only reviews matching this filter. Omit for all. One of: `1`, `2`, `3`, `4`, `5`, `positive`, `critical`.
`max_results`	integer	no	How many reviews to deliver at most (1–20). You pay only for delivered reviews.

Outputs — 17 fields, one row per review

What people build with the Amazon reviews API

Three shapes of work this endpoint was designed around.

Review mining for product teams

Pull critical-filtered reviews for your ASINs and the complaint themes arrive pre-ranked by helpful votes, with the variant column pointing at which configuration fails.

Competitor listing analysis

Top-sorted reviews are the arguments Amazon itself puts in front of buyers — the exact language that sells the rival product, ready for positioning work.

Verified-share auditing

The verified and Vine flags per row make review-quality measurable: what share of a listing's praise is purchase-backed, per marketplace.

Amazon reviews API versus rolling your own

The differences that actually cost time when you build this in-house.

	DIY scraper	This collector
Flags	Badges to parse out of markup	verified_purchase, vine, helpful_votes as typed columns
Marketplaces	One domain hard-coded	ASIN + country: .com, .it, .de, .co.uk and the rest

Amazon reviews API: the POST to the amazon_reviews collector, 10 reviews delivered and the bill, 10 × $0.002 = $0.02 in usage.cost_usd; zero reviews would cost $0. — The same call you would paste into a terminal: a Bearer key, product, country and sort in the body, and back the envelope every QuanticData endpoint returns — type, message, payload — where count is how many reviews arrived and usage.cost_usd is $0.02, which is 10 × $0.002. A run that delivers nothing costs nothing. The key is good for 60 req/min on the free tier.

FAQ

Questions we get about the Amazon reviews API.

Something else? Ask us

How many reviews can I get per product?

The reviews published on the product page: typically 8 to 13 per product, at most 20 per run. The notes always state how the run ended.

Can I filter to critical reviews only?

Yes — stars accepts 1–5, positive or critical, applied by Amazon before parsing, so a critical-only pull spends nothing on praise.

Which marketplaces are supported?

Any Amazon storefront the search collectors support: pass country (us, it, de, uk, fr, es, ca, jp…) and the matching domain is used, with the review's own country also parsed from its date line.

Is this allowed?

The collector reads public pages only and never logs in. You get what any signed-out visitor sees, structured.

Is there a free Amazon reviews API?

Every account gets $2 of credit every month with no card, which is about 1,000 delivered reviews on this endpoint at $0.002 each. It renews monthly, and a run that delivers nothing is never billed — so a failed or blocked attempt does not eat the allowance.

How much does one run cost?

Multiply the rows you actually receive by $0.002. A run capped at 20 reviews — the maximum for this collector — costs $0.04 if every row comes back, and less when the source has fewer. Volume tiers take up to 30% off, and GET /v1/scraper/collectors returns the price your key actually pays.
