How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
Returns the upstream Walmart SERP response, including product listings with titles, prices, ratings, and URLs as returned by the underlying data source, passed through after successful x402 micropayment authorization.
Example use cases
Price comparison for a specific product
“Can you search Walmart for 'Samsung 65 inch 4K TV' and show me the top results with prices so I can compare deals?”
Finding in-demand items for resale research
“Look up Walmart search results for 'LEGO Star Wars sets' and tell me what products are showing up and at what prices.”
Automated product availability check
“Check Walmart for 'Ninja Air Fryer 6 quart' and pull back whatever product listings come up — I want titles, prices, and links if available.”

Choose this endpoint when you need programmatic access to Walmart product search results (SERP data) on a pay-per-call basis using the x402 micropayment protocol, especially useful for agents that need Walmart-specific product pricing, availability, or catalog data without a subscription-based API contract.
Side effects
- Payment failure: insufficient USDC balance or x402 payment rejected — no results returned
- Invalid query path or malformed request body — upstream may return an error or empty results
- Upstream Walmart SERP provider unavailability — gateway may return a 502 or timeout
- Rate limiting by the upstream provider — may return throttling errors
- Empty result set if the query matches no Walmart products
