## 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-seller-reviews-api-9064fe63
```

Example prompt: Can you pull the latest customer reviews for Amazon seller ID 'A1B2C3D4E5' so I can see how buyers rate them before I consider purchasing?

## When to prefer this

Choose this endpoint when you need real-time Amazon seller review data without setting up an account or managing API keys, and when per-call micropayment pricing ($0.003 USDC) is acceptable. Ideal for one-off lookups, agent workflows, or low-volume monitoring where a subscription-based scraping service would be overkill.

## Known failure modes

- Invalid or non-existent seller ID returns empty results or error
- Amazon rate limiting or anti-scraping measures may cause intermittent failures
- Payment failure over x402 protocol results in 402 response and no data returned
- Network timeouts if Amazon pages are slow to load
- Region-specific seller IDs may not resolve if marketplace is not specified
