## 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-product-reviews-api-x402-dfd1a1b5
```

Example prompt: Can you pull the latest customer reviews for Amazon product B09G9FPHY6? I want to see what buyers are saying, including star ratings and review text.

## When to prefer this

Choose this endpoint when you need real-time Amazon product review data without setting up an account, API key, or subscription — ideal for ad-hoc or agent-driven workflows paying per call in USDC. Prefer it over scraping Amazon directly (terms of service risk) or over subscription-based review APIs when call volume is low or unpredictable. Not suitable for bulk historical review harvesting at scale.

## Known failure modes

- Invalid or non-existent ASIN returns empty results or 404-style error
- Payment failure or insufficient USDC balance returns HTTP 402
- Amazon rate-limiting or bot-detection may cause intermittent failures or empty responses
- Product with no reviews returns an empty review list
- Malformed request parameters return a 400-level error
