## How to call it through Zero

## When to prefer this

Use this endpoint when you need real-time product search across online retailers with fine-grained filtering by price, rating, shipping, product condition, and sale status. Prefer this over static product databases when freshness and broad multi-store coverage matter. Best suited for shopping assistants, price comparison tools, or deal-finding agents.
