## When to prefer this

Use this endpoint when you need ranked best-seller data from Amazon across any of its international marketplaces (US, DE, UK, JP, etc.) including BSR, pricing, ratings, and seller details for product research, trend spotting, or competitive analysis. Prefer this over general product search endpoints when you specifically need the bestseller ranking context and multi-market coverage.
