What is Review Bulk-fetch?
Review Bulk-fetch is the Scavio endpoint that returns up to 1000 reviews per call for a target ASIN, Walmart item, or Google Maps place, with normalized fields for rating, author, date, verified-purchase flag, and review body. Designed for review-mining pipelines that need a wide sample before classification. Pagination and deduplication are handled server-side, so callers get one clean result set rather than stitching multiple pages.
Example Response
JSON
{ "asin": "B0X", "review_count": 842, "reviews": [{ "rating": 4, "verified": true, "date": "2026-03-12", "body": "..." }] }Use Cases
- Review mining for product roadmap input

Why Review Bulk-fetch Matters
Review mining requires breadth to avoid sampling bias; bulk-fetch cuts what used to be a multi-page scraping job to a single call with clean JSON.
