Amazon Reviews reads buyer reviews from a product link. Each row carries the review title and text, rating, publish time, how many people found it helpful, whether it is a verified purchase, whether it came through the Vine program, the variant bought and the reviewer's country. Use it to learn whether buyers are happy and what exactly they complain about, for cross-border product research, mining a competitor's weak points or monitoring your own products.

Pass a product link such as /dp/<ASIN>; the ASIN is taken from it. For stores outside the US, set `domain` to the store that matches the link, such as amazon.co.uk. Weight verified purchases more heavily, label `is_vine` reviews as free-product reviews, and use `variant` to tie feedback to a specific version. There is no sort or paging parameter. On every store only the featured reviews shown on the product page are available, usually about a dozen per product, not the full history.

## Parameters

| name | type | required | default | description |
|---|---|---|---|---|
| url | not declared | yes | not declared | Specifies an Amazon product URL, such as https://www.amazon.com/dp/<ASIN>. The reviews action extracts a 10-character uppercase alphanumeric ASIN from /dp/, /gp/product/, or /product-reviews/ paths; store homepages are not supported. For this parameter, profile fetches the product details page rather than user profile data. |
| domain | enum: amazon.ca / amazon.co.jp / amazon.co.uk / amazon.com / amazon.com.au / amazon.de / amazon.es / amazon.fr / amazon.in / amazon.it / amazon.sg | no | not declared | The Amazon country store the reviews come from, without a scheme, `www.` or path. It defaults to `amazon.com` and should match the store in the product URL. Only 11 stores are supported: `amazon.com`, `amazon.co.uk`, `amazon.de`, `amazon.fr`, `amazon.it`, `amazon.es`, `amazon.ca`, `amazon.com.au`, `amazon.in`, `amazon.co.jp` and `amazon.sg`. Any other store, such as `amazon.com.mx`, is rejected with 422 `invalid_value` before anything is charged, and the error lists the supported stores. On every store, reviews returns only the featured reviews shown on the product page, usually about a dozen per product, not the full review history. Reviews from the US store (`amazon.com`, also the default when `domain` is omitted) are currently unavailable because Amazon requires a login to view them, and these requests are not charged; synchronous calls usually return 503 `unavailable` with `error.reason` set to `access_blocked`. The other 10 stores work as usual; for a product also sold on another store, such as `amazon.ca` or `amazon.co.uk`, pass that store's `domain` to get its reviews. |
| limit | integer (1–100) | no | 20 | The most rows to return in this call, an integer from 1 to 100. The default applies when you leave it out, and a call can return fewer rows. Larger values are accepted and capped at the maximum. |

## Response fields (items in `results`)

| field | meaning |
|---|---|
| review_id | Review ID. |
| title | Title. null when the platform has no titles (for example text-only posts). |
| text | Body text with HTML removed, returned in full and never cut short (on a few platforms the list results themselves carry only an excerpt; the platform's field notes say so). |
| rating | Rating. **The scale varies by platform**: rating_scale on the same row gives the maximum (usually 5; Booking, Douban, iQIYI and NAVER use 10). Convert with rating_scale before comparing across platforms, or the comparison can come out backwards. |
| rating_scale | Maximum of rating in the same row: 5 for five-star scales, 10 for ten-point scales. Present only when the row has a rating. |
| posted_at | Publish time in ISO 8601, UTC (for example 2026-08-07T12:34:56+00:00). Non-standard strings from the platform are passed through as is, so parse defensively. null means the platform does not disclose it. |
| helpful_count | How many times the review was marked helpful. |
| is_verified_purchase | Whether the review is from a verified purchase. Give unverified reviews less weight. |
| is_vine | Whether the review comes from the Vine program (the platform sends the product for testing, and the review is labeled as such). |
| variant | Product variant the review refers to. |
| country | Country or region: a full name or an ISO code depending on the platform, not normalized. |
| url | Link to the record on the platform. |
| author_name | Reviewer's public display name (reviews), taken from the reviewer's public profile; may be empty. |
| author_id | Reviewer's public Amazon profile ID (reviews); may be empty. |
| author_avatar_url | Avatar link from the reviewer's public profile (reviews); may be empty or a default avatar. |
| product_asin | Product ASIN. |
| platform | Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok). |
| images | Array of image links in the platform's display order; absent when there are no images. |

## FAQ

### How do I read reviews from a non-US store?

Set `domain` to the store, for example amazon.co.uk or amazon.co.jp, matching the store in the product link, without https:// or a path. It defaults to amazon.com, so reviews for another store's product will not line up without it.

### Which reviews should I trust most?

Give priority to reviews where `is_verified_purchase` is true and discount the rest. Reviews with `is_vine` true come from Amazon's Vine program and should be labeled as such. A high `helpful_count` usually marks a representative review.

### Can I pass a storefront link as `url`?

No. The ten-character ASIN is read from a /dp/, /gp/product/ or /product-reviews/ path, so pass a product or review page link. Storefronts and search pages return no reviews.
