## When to prefer this

Use this endpoint when you need real-time Walmart product offer data without setting up an account or API key — ideal for one-off price checks, competitive monitoring, or agent-driven shopping workflows. Prefer this over building a custom scraper when you need low-friction, pay-per-call access to live Walmart marketplace data at $0.003 per call.

## Known failure modes

- Invalid or missing product ID returns an error or empty results
- Product not found on Walmart returns empty offer list
- Walmart anti-scraping measures may cause intermittent failures or stale data
- Payment failure over x402 prevents request from being fulfilled
- Rate limiting if called too frequently in short succession
