## When to prefer this

Use this endpoint when you need live, cross-seller price comparison for a specific product in a single API call, especially for deal-finding agents, repricing bots, or shopping assistants that need the cheapest offer and price distribution without building their own scraping pipeline. Prefer it over static product databases or search APIs that don't return real-time pricing data.

## Known failure modes

- Product query returns no listings — sellers may not carry the item or scraping blocked
- Stale or inaccurate prices if seller pages changed between scrape and parse
- Residential-IP scraping may be rate-limited or geo-blocked for certain retailers
- Ambiguous product queries may return irrelevant listings
- Payment not processed — 402 response if USDC payment header is missing or invalid
