Endpoint
GEThttps://x402.openwebninja.com/real-time-ebay-data/products-by-categoryWhen to prefer
Use this endpoint when you need real-time eBay product listings scoped to a specific category, with rich filtering options like price range, condition, buying format, and sorting. Prefer this over generic product search when you already know the eBay category ID and need structured product data including seller metrics.
