## 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-product-reviews-api-0ba5e7d0
```

Example prompt: Can you pull the latest Amazon customer reviews for the product with ASIN B08N5WRWNW? I want to see the review text, star ratings, and whether each review is a verified purchase.

## When to prefer this

Choose this endpoint when you need real-time Amazon product review data without registering for an Amazon API key or managing OAuth credentials. It is ideal for ad-hoc competitive research, sentiment analysis pipelines, or AI agents that need to pull customer feedback on demand. The x402 micropayment model at $0.003/call makes it cost-effective for low-to-medium volume use cases where a subscription API would be overkill.

## Known failure modes

- Invalid or non-existent ASIN returns empty results or error
- Product with no reviews returns empty review array
- Amazon temporarily blocking scrape results in incomplete or stale data
- Payment failure via x402 results in 402 response before data is returned
- Rate limiting if too many rapid sequential calls are made
