# Amazon reviews API

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.

You send product and country; the run goes out through a residential exit and comes back as reviews with rank, page and review_id — 16 fields on every row — and you are billed $0.002 for each review actually delivered, nothing for a run that delivers none.

## 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 honesty note, on the page itself because it affects what you should expect: Amazon has been walling deep review pagination behind login since 2024. This collector delivers every page Amazon serves publicly and, when the wall appears, falls back to the reviews embedded in the product page and says so in the run notes — typically 10–30 reviews per product land, more when Amazon serves extra pages, and a run never pretends otherwise.

## What one review looks like

Every delivered review carries these fields. Nullable means the source did not publish it — the field stays empty instead of being guessed.

| Field | Type | What it holds |
| --- | --- | --- |
| `rank` | integer | 1-based position in the requested order. |
| `page` | integer | Reviews page the row came from. |
| `review_id` | string · nullable | Amazon review id. |
| `title` | string · nullable | Review title. |
| `text` | string · nullable | Full review text. |
| `rating` | number · nullable | Star rating (1–5). |
| `date` | string · nullable | Review date (YYYY-MM-DD when parseable). |
| `date_raw` | string · nullable | The date line as shown. |
| `country` | string · nullable | Marketplace country from the date line. |
| `author` | string · nullable | Reviewer display name. |
| `verified_purchase` | boolean | True when marked Verified Purchase. |
| `helpful_votes` | integer | People who found the review helpful. |
| `variant` | string · nullable | Purchased variant (size, colour…) when shown. |
| `vine` | boolean | True for Amazon Vine reviews. |
| `images` | string[] | Review image URLs (empty when none). |
| `url` | string · nullable | Direct link to the review. |

## 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 (1–100). You pay only for delivered reviews. |

Integration

## One POST, typed rows

Base URL `https://api.quanticdata.io/v1`, Bearer auth, the same key as every other Data API. Endpoint: `POST /v1/scraper/collectors/amazon_reviews/run`.

```
curl -X POST https://api.quanticdata.io/v1/scraper/collectors/amazon_reviews/run \
  -H "Authorization: Bearer $QD_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"product":"B07FZ8S74R","country":"us","max_results":10}'

## 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 |
| --- | --- | --- |
| Login wall | A signin redirect that breaks your crawler | Detected, worked around via the product page, reported in notes |
| 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 |

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 →](mailto:hello@quanticdata.io)

### How many reviews can I get per product?

Every review Amazon serves without login: commonly the first pages plus the product page's embedded top reviews — around 10–30 per product in practice. When Amazon serves more public pages, the run keeps paginating up to your max_results, and 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, never logs in and never bypasses the wall — behind-login content stays behind login. 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 100 reviews — the maximum for this collector — costs $0.2 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.

## Run the Amazon reviews API now
