## 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-best-sellers-realtime-data-97095243
```

Example prompt: What are the current best-selling products in Amazon's Kitchen & Dining category? Pull the top rankings for me right now.

## When to prefer this

Choose this endpoint when you need live Amazon best-seller data without setting up an account or API key — ideal for one-off lookups, agent workflows, or pay-as-you-go market research. At $0.003 per call, it's cost-effective for sporadic queries. Prefer this over full Amazon product search APIs when you specifically want ranked best-seller lists rather than keyword search results.

## Known failure modes

- Invalid or unsupported Amazon category returns empty results or 400 error
- Payment failure via x402 (insufficient USDC balance or unsupported chain) blocks the request
- Amazon anti-scraping measures may occasionally cause transient failures or stale data
- Malformed query parameters return 400 with schema validation error
- Network timeout if Amazon data source is temporarily slow
