## How to call it through Zero

```sh
zero fetch --capability dealpulse-best-price-finder-8f393395
```

Example prompt: What's the absolute cheapest place to buy the Sony WH-1000XM5 headphones right now, and are there any coupon or promo codes I can use — include a link to buy?

## When to prefer this

Use this endpoint when you need the single best price across all retailers for a specific named product, along with coupon codes and a ready-to-use buy link. Prefer this over the price-comparison sibling when you want a definitive 'best deal' recommendation rather than a full multi-retailer price table.

## Known failure modes

- Product not found or unrecognized product name — returns empty results or 404
- No deals currently indexed for the product — returns empty deal list
- Ambiguous product name matching multiple SKUs — may return results for wrong variant
- Retailer data temporarily stale — prices may not reflect last-minute changes
- Payment failure or x402 auth error — request rejected before processing
