Example prompt: Can you pull up the full product details for Walmart product ID 123456789 — I need the title, price, description, and manufacturer in structured format?

## When to prefer this

Use this endpoint when you need structured product data from Walmart by product ID, especially for price lookups, catalog enrichment, or comparison workflows. Prefer this over Walmart search endpoints when you already have the product ID and need full detail rather than a list of results.

## Known failure modes

- Invalid or non-existent product ID returns an error or empty result
- Product not available in specified store returns no store-specific data
- Rate limits or upstream Walmart changes may cause intermittent failures
- Unsupported device type value may cause unexpected behavior
