Example prompt: Can you pull customer reviews for Amazon seller ID A2L77EE7U53NWQ on the US marketplace, filter to only 1-star and 2-star critical reviews, and include AI sentiment analysis so I can see what emotions are driving the negative feedback?

## When to prefer this

Use this endpoint when you need to programmatically retrieve Amazon seller reviews by seller ID, especially when you want to filter by star rating across multiple international marketplaces or enrich reviews with AI-powered emotion sentiment analysis. Prefer this over manual scraping or general web search when structured, paginated review data with optional sentiment scoring is required.

## Known failure modes

- Invalid or non-existent seller ID returns empty results or error
- Unsupported country code returns validation error
- Page number out of range (>50) returns validation error
- Seller has no reviews returns empty list
- Rate limiting or upstream Amazon changes may cause transient failures
