Endpoint
GEThttps://openwebninja-x402.vercel.app/api/amazon/product-reviewsWhen to prefer
Use this endpoint when you need structured Amazon review data for a specific product ASIN, especially when filtering by star rating, sort order, or country marketplace is required. Prefer this over general web scraping when you need clean, paginated review output with verified-purchase filtering.
Side effects
- Invalid or non-existent ASIN returns empty results or error
- Unsupported country code results in validation error
- Page number out of range returns empty results
- Amazon rate-limiting or scraping blocks may cause intermittent failures
- Payment failure (HTTP 402) if USDC balance is insufficient
