## How to call it through Zero

## When to prefer this

Use this endpoint when you need to retrieve structured customer reviews for a specific Walmart product by its product ID, especially when you need filtering by rating or sorting by recency/relevancy. Prefer this over general search endpoints when you already have the product ID and want review-specific data.

## Known failure modes

- Invalid or nonexistent product_id returns empty results or 404
- product_id is required — omitting it causes a validation error
- limit out of range (must be 1-50) causes a schema validation error
- page below 1 causes a validation error
- Invalid sort enum value causes a bad request error
- Domain must be 'us' or 'ca' — other values fail validation
- Payment failure (x402) if USDC balance is insufficient
