## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability openweb-ninja-amazon-promo-code-details-0aa26174
```

Example prompt: Can you look up the details for the Amazon promo code SAVE20 — I want to know the discount amount, what it applies to, and whether it's still valid?

## When to prefer this

Use this endpoint when you need real-time Amazon promotional code details without requiring an Amazon account or API key. It is ideal for price comparison tools, shopping assistants, or coupon aggregator agents. At $0.003 per call with x402 micropayments, it suits pay-per-use workflows where bulk API subscriptions are not cost-effective.

## Known failure modes

- Invalid or expired promo code returns empty or error response
- Promo code not found on Amazon returns null result
- Network timeout if Amazon's underlying data source is slow
- Rate limiting if too many requests made in quick succession
- Payment failure via x402 if insufficient USDC balance
