How this service works
Get Amazon product reviews by ASIN or URL: review text, star rating, title, author, date, verified-purchase and Vine flags, helpful votes and variant, plus the product star-rating breakdown. Async: a first call with asin returns a snapshot id (collection ~40s); call again with that snapshot to fetch reviews. For review mining, sentiment, complaint detection and competitor weakness analysis. 亚马逊评论挖掘与差评分析。 Accepts payment on Base or Solana — either network works.
Output
On first call with an ASIN or URL, returns a snapshot ID (collection takes ~40 seconds). On second call with the snapshot ID, returns a list of reviews each containing: review text, star rating (1-5), title, author name, date, verified-purchase flag, Vine flag, helpful votes count, product variant, plus an aggregate star-rating breakdown (count per star level) for the product.
Example use cases
Example prompt

Technical details
Endpoint
GEThttps://api.x402node.dev/ecom/reviewsWhen to prefer
Use this endpoint when you need structured Amazon review data including per-review metadata (verified purchase, Vine, helpful votes, variant) and the aggregate star-rating breakdown — especially for review mining, sentiment analysis, complaint detection, or competitive weakness analysis. Prefer over generic web scraping when you need clean, parsed review fields rather than raw HTML.
Side effects
- Invalid or non-existent ASIN returns an error or empty review set
- Snapshot ID not yet ready returns a pending/retry status — caller must wait ~40s before polling
- Amazon throttling or access restrictions may cause incomplete data
- Product with no reviews returns an empty reviews array
- Malformed URL input fails parameter validation
- Payment failure (insufficient USDC) results in 402 rejection before any data is returned
