## 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 amazon-sellers-offers-lookup-by-asin-381e22f1 -d '<json body>'
```

Example prompt: Can you pull all the current seller offers for Amazon ASIN B0HCXW6CDR — I want to see who's winning the buy box, what the third-party sellers are charging, their conditions (new or used), and their seller ratings?

## When to prefer this

Use this endpoint when you need real-time seller-level pricing data for a specific Amazon ASIN — especially for buy-box tracking, competitive repricing, price arbitrage, or presenting shoppers with the cheapest available offer. Prefer this over a product detail endpoint when seller identity, condition, rating, and per-seller pricing matter more than general product metadata.

## Known failure modes

- Invalid ASIN format (not 10 alphanumeric uppercase characters) returns a validation error
- ASIN exists on Amazon but has no active offers — returns empty results
- ASIN not found on Amazon US marketplace returns empty or error
- Transient Amazon data unavailability may result in stale or missing offer data
- Payment failure (insufficient USDC balance) blocks the request via x402

## How this service works

Amazon offers & sellers API (US) by ASIN: the buy-box winner plus third-party sellers, each with seller name, price, regular price, discount, condition (new/used), ships-from and seller rating. Amazon offers and sellers for buy-box tracking and price comparison. No offers returns empty results.

## Output

A list of seller offers for the given ASIN, each including the seller name, current price, regular (list) price, discount amount or percentage, product condition (new/used), ships-from location, and seller rating. The buy-box winner is identified. If no offers exist, an empty result set is returned.
