## How to call it through Zero

```sh
zero fetch --capability dealpulse-store-coupons-cashback-api-afbaf34b
```

Example prompt: Can you check if there are any working coupon codes, promo codes, or cashback deals available for Nike right now before I check out?

## When to prefer this

Use this endpoint when a user wants to save money at a specific retailer or restaurant by finding active coupon codes, promo codes, or cashback rates before making a purchase. Prefer this over price comparison endpoints when the user already knows where they want to shop and just wants discounts.

## Known failure modes

- Store not found or not supported — returns empty results or 404
- No active coupons currently available for that retailer
- Store name ambiguous (e.g. multiple retailers with similar names) — may return wrong store
- Network timeout if upstream deals data provider is slow
- Payment failure (x402) if USDC balance is insufficient
