Endpoint
GEThttps://x402.openwebninja.com/realtime-ecommerce-data/walmart/searchWhen to prefer
Use this endpoint when you need real-time Walmart product search results with rich metadata including pricing, availability, ratings, and seller info. Prefer over static datasets when current inventory and pricing accuracy matter. Choose this over general web search when you need structured, machine-readable product data specifically from Walmart rather than aggregated shopping results.
