Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

## When to prefer this

Use this endpoint when you need to programmatically check whether a specific product is available at Walmart, particularly in agentic workflows that require real-time or near-real-time stock verification before making purchase decisions or recommendations. Prefer this over general web search when you need structured inventory data rather than web page content.

## Known failure modes

- Product not found in Walmart catalog — returns empty or no-match result
- Ambiguous query string yields incorrect or irrelevant product match
- Walmart API or scraping layer unavailable — service timeout or error
- Rate limiting or payment failure at the x402 layer — request not processed
- Out-of-date inventory data returned due to caching delays
