## 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-252145c5
```

Example prompt: Pull the current top products listed under Amazon's 'Kitchen & Dining' category so I can see what's available, with prices and ratings.

## When to prefer this

Use this endpoint when you need real-time Amazon product listings for a specific category without a registered Amazon API key or seller account. It is ideal for price monitoring, competitor research, trend analysis, and building product feeds or deal aggregators. Prefer this over the Amazon Product Advertising API when you want zero-setup, pay-per-call access via x402 and don't need personalized recommendations or cart integration.

## Known failure modes

- Invalid or unrecognized category identifier returns empty results or error
- Amazon temporarily blocks scraping for a category, returning a 503 or partial response
- Payment via x402 fails due to insufficient USDC balance, preventing the request
- Rate limiting if the same category is requested too frequently in a short window
- Category has no products or is deprecated on Amazon, returning an empty list
