## 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-products-by-category-8dc3a4e8
```

Example prompt: Can you pull the current Amazon product listings in the 'Wireless Headphones' category so I can compare what's available and their prices right now?

## When to prefer this

Choose this endpoint when you need live Amazon product data for a specific category without setting up your own scraper or managing API keys. It's ideal for price intelligence, competitive research, catalog discovery, and trend analysis on Amazon. At $0.003 per call with no account required, it suits agents making on-demand or low-frequency lookups. Prefer alternatives if you need order management, seller-side data, or structured bulk catalog exports.

## Known failure modes

- Invalid or unrecognized category identifier returns empty results or error
- Amazon temporarily blocks or rate-limits the scraping layer, causing 503 or empty response
- Payment over x402 fails due to insufficient USDC balance or unsupported network, resulting in 402 rejection
- Category with no products returns empty array
- Network timeout if Amazon's servers are slow
