Amazon Reviews API: Async Structured Data in Java

Scrape Amazon product reviews into structured data JSON/CSV with ScraperAPI async in Java. Extract ratings, verified purchases, and sentiment analysis by ASIN.

Amazon review pages currently require a login to access. Since ScraperAPI does not support scraping behind a login, this endpoint is not available.

Please use the Amazon Product Page API instead to scrape all publicly available reviews for an Amazon product.

This endpoint will retrieve reviews for a specified product from an Amazon reviews page and transform it into usable JSON.
