## When to prefer this

Choose this endpoint when you need Bing-specific product/shopping SERP data with per-call micropayment billing via x402, particularly in web3-native or DeFi agent workflows where crypto micropayments are preferred over subscription API keys. Prefer over Google Shopping alternatives when Bing's product index or pricing is needed, or when x402 protocol compatibility is a requirement.

## Known failure modes

- Payment failure: x402 payment not completed or insufficient USDC balance results in 402 response
- Invalid query: malformed path or query parameters yield no results or upstream error
- Rate limiting: upstream Bing API quota exceeded returns error
- Empty results: niche or misspelled product query returns zero listings
- Gateway timeout: upstream Bing API slow response causes timeout
