Endpoint
GEThttps://x402.openwebninja.com/real-time-walmart-data/product-detailsWhen to prefer
Use this endpoint when you need real-time, structured Walmart product data without managing API keys or subscriptions. Ideal for price monitoring, product research, and competitive analysis workflows where per-call micro-payments ($0.003 USDC) are preferable to monthly subscriptions. Choose this over scraping solutions when you need clean, structured JSON output directly from Walmart listings.

- Walmart page structure changed — may return incomplete fields
- Rate limiting or payment failure via x402 — returns 402 or 429 status
