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 body containing structured product search results, including product names, prices, ratings, and URLs as returned by the underlying search data provider. The content type is passed through from the upstream source.
Example use cases
Price comparison for a specific product
“Search Walmart for 'KitchenAid stand mixer' and show me the top results with prices so I can compare them to other retailers.”
Finding deals on household items
“Look up 'paper towels bulk' on Walmart and list the cheapest options available in the search results.”
Product research for e-commerce reselling
“Can you pull the Walmart search results for 'bluetooth speaker outdoor' and give me the product names, prices, and URLs from the first page?”

Endpoint
POSThttps://quanta-roan.vercel.app/api/service/serp-walmart?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic access to Walmart product search results on a per-query, pay-as-you-go basis via x402 micropayments (USDC). It is best suited for agents that need real-time Walmart SERP data without a subscription, especially in web3/DeFi-native workflows where crypto micropayments are preferred over API keys.
Side effects
- Payment failure: insufficient USDC balance or x402 payment not accepted, resulting in a 402 Payment Required response
- Invalid query parameters: malformed path or query object leads to upstream error
- Upstream unavailability: Walmart search data provider is down or rate-limiting, returning 5xx errors
- Empty results: valid query returns no product listings for obscure or misspelled search terms
- Timeout: upstream response takes too long, resulting in a gateway timeout error
