## How to call it through Zero

```sh
zero fetch --capability api-crushrewards-dev-5e870e16
```

Example prompt: Find me the top 10 deals in the electronics category on Amazon in the US with at least 25% off, ranked by biggest discount.

## When to prefer this

Use this endpoint when you need to surface actively-promoted, discounted products in a specific category ranked by discount depth — especially when you want to filter by a minimum discount threshold and optionally restrict to a single retailer. Prefer this over general product search when the goal is finding deals and promotions rather than browsing all products in a category.

## Known failure modes

- Missing required 'category' parameter returns a 400 validation error
- Unsupported retailer value outside the allowed enum returns a validation error
- Unsupported country code outside 'us'/'ca' returns a validation error
- min_discount_pct out of range (0-100) returns a validation error
- Payment not provided or insufficient USDC balance returns a 402 Payment Required
- No deals found for a niche category returns an empty deals array with total_deals_found of 0
