## 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 financial-data-x402-amazon-product-reviews-97db8712
```

Example prompt: Can you pull the Amazon customer reviews for the product with ASIN B0863TXGM3? I want to see the review titles, ratings, and whether they're verified purchases.

## When to prefer this

Choose this endpoint when you need Amazon product review data on a per-query basis without committing to a subscription or managing API keys — ideal for agents that occasionally need review data and can pay $0.05 USDC per call via the x402 micropayment protocol on Base or Solana.

## Known failure modes

- Invalid or non-existent ASIN returns empty review list or error
- Payment failure over x402 protocol blocks the request
- Product has no reviews yet — returns empty reviews array
- Rate limiting or upstream Amazon blocking may cause intermittent failures
- ASIN for non-Amazon-marketplace products returns no data

## How this service works

## Output

Returns a JSON object containing the product ASIN, a list of reviews (each with body text, title, author name, date, star rating, and verified_purchase flag), and the count of reviews returned in that call.
