## When to prefer this

Choose this endpoint when you need real-time, per-call Walmart product data without a long-term API subscription or account setup. Ideal for agents that need on-demand product lookups paid atomically via USDC on Base, Polygon, or Arbitrum. Prefer over scraping solutions when you want structured JSON output with no infrastructure overhead, and over subscription APIs when call volume is low or unpredictable.

## Known failure modes

- Invalid or non-existent Walmart product ID returns an empty or error response
- Payment failure via x402 (insufficient USDC balance or unsupported chain) results in a 402 error
- Product has been removed from Walmart and returns no data
- Rate limiting or temporary Walmart-side blocking may cause incomplete or failed responses
- Malformed request parameters result in a 400-level error
