## 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 openwebninja-amazon-product-seller-offers-8080da4f
```

## When to prefer this

Use this endpoint when you need to retrieve all available seller offers for a specific Amazon product by ASIN, particularly for price comparison, seller research, or finding the best deal across multiple sellers. Prefer this over the product details endpoint when you specifically need seller-level offer data rather than general product metadata.

## Known failure modes

- Missing required 'asin' parameter returns 400 bad request
- Payment failure via x402 protocol returns 402 Payment Required
