Example prompt: Can you pull the real-time product details from Walmart for item ID 123456789 — I need the current price, availability, and any customer ratings?

## When to prefer this

Use this endpoint when you need real-time, structured Walmart product data without managing API keys or subscriptions. Ideal for price monitoring, product research, and competitive analysis workflows where per-call micro-payments ($0.003 USDC) are preferable to monthly subscriptions. Choose this over scraping solutions when you need clean, structured JSON output directly from Walmart listings.

## Known failure modes

- Walmart page structure changed — may return incomplete fields
- Rate limiting or payment failure via x402 — returns 402 or 429 status
- Invalid input parameter format — returns 400 error
