Endpoint
GEThttps://x402.openwebninja.com/realtime-ecommerce-data/walmart/products-by-categoryWhen to prefer
Use this endpoint when you need to browse or list Walmart products within a known category ID, especially when you want to apply filters like price range, location (zip/state/store), sorting preference, or domain (US vs Canada). Prefer this over keyword search endpoints when you already know the category and want structured product catalog data with rich metadata including ratings, shipping, and availability.
