## When to prefer this

Use this endpoint when you need structured, paginated Walmart customer review data for a specific product ID, especially when you need filtering by star rating or sorting by relevancy, recency, or rating. Prefer this over scraping Walmart directly or using generic review aggregators when you need reliable, schema-consistent review data from Walmart's US or Canadian storefronts.

## Known failure modes

- Product not found on the specified domain (us/ca) returns empty reviews array
- Page number exceeds total_pages returns empty data
