Features

✓

7 reviews per page with full body text

Each /v1/amazon/product-reviews call returns up to 7 reviews with the complete body text — title, rating, author, date — and you page deeper with the page parameter.

✓

Overall rating distribution (% per star)

Returns rating_distribution as a percentage breakdown per star (e.g. {1:11, 2:3, 3:5, 4:12, 5:69}) plus total_ratings, so you can render a star histogram without aggregating reviews yourself.

✓

Filter by star rating, verified purchase, or media

Narrow the feed to a specific star level, to verified-purchase reviews only, or to reviews that include photos and video — ideal for trust widgets and sentiment sampling.

✓

Variant metadata on each review (size, color, etc.)

Each review carries the variant it was written for (size, color, configuration), so you can attribute feedback to the exact product variation.

✓

Amazon Vine program flag

Flags reviews submitted through the Amazon Vine program so you can separate incentivized early-reviewer feedback from organic customer reviews.

The Amazon Reviews API for ratings and sentiment

The YepAPI Amazon Reviews API pulls customer reviews for any ASIN as structured data. Send an ASIN to /v1/amazon/product-reviews and get back up to 7 reviews per page — each with full body text, star rating, author, date, helpful votes, the variant it was written for, and a Vine-program flag — plus the overall rating_distribution as a percentage per star, all at $0.01 per call.

This is a different job from product details: where Product Details describes the item, Reviews captures what customers actually said about it. Sort by TOP_REVIEWS or MOST_RECENT, filter to verified purchases or reviews with media, and page through to feed sentiment analysis, competitive research, or review-summary widgets.

What is an Amazon Reviews API?

An Amazon Reviews API returns the customer reviews attached to a product as structured data rather than scraped HTML. For a given ASIN you receive an array of reviews — review_id, title, star rating, author, date, verified-purchase status, helpful votes, the product variant reviewed, and a Vine flag — alongside the listing's aggregate rating_distribution and total_ratings. It exists because review text is the richest qualitative signal on Amazon, and pulling it reliably at scale is exactly the kind of layout-sensitive scraping that a stable API removes from your plate.

Build your own review-analysis tool

Feed review bodies straight into an LLM for sentiment and feature extraction, or build a "reviews summary" widget for an affiliate site. Page through with the page parameter, sort by MOST_RECENT to catch new feedback, and filter to verified purchases to cut noise. Because reviews and the YepAPI AI endpoints share one key, you can fetch reviews and run summarization in the same workflow — no second vendor, no second invoice.

Amazon Reviews API pricing — $0.01 per call

Reviews cost $0.01 per call, and each call returns up to 7 full-text reviews plus the rating distribution. There are no quotas or monthly minimums — paginate as deep as you need and pay only per page fetched. Keepa offers only limited review access and Rainforest API meters per request; YepAPI's flat per-call rate makes harvesting an entire review history for sentiment analysis cost-predictable down to the page.

Filters, distribution, and Vine signals

What makes Reviews distinct is the metadata around each opinion. The rating_distribution lets you render a star histogram instantly, the verified-purchase and media filters let you isolate the most trustworthy feedback, variant metadata ties each review to a specific size or color, and the Vine flag separates incentivized early reviews from organic ones. Together those signals let you weight sentiment by trust instead of treating every review equally.
