## 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 ragradar-grid-amazon-seller-reviews-94a30d29
```

Example prompt: Pull all the customer reviews for Amazon seller ID A2Z3J4K5L6M7N8 — I want to see what buyers are saying about them.

## When to prefer this

Use this endpoint when you need programmatic, pay-per-call access to Amazon seller review data without managing Amazon API credentials directly. Best for e-commerce intelligence tasks, seller vetting, competitor research, or due diligence where per-call pricing ($0.75 USDC) is acceptable and USDC/Base micropayments via x402 are supported.

## Known failure modes

- Invalid or non-existent sellerId returns empty data or error
- Payment failure via x402/USDC micropayment blocks the request
- Rate limiting if too many calls are made in quick succession
- Stale data if the seller has very recent reviews not yet indexed
- Malformed sellerId path parameter results in a 400 or 404 response
