## 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 asin402-product-price-sales-data-by-asin-7e400d8b
```

Example prompt: What's the current buy box price and 90-day price average for ASIN B08N5WRWNW on the US Amazon marketplace, and roughly how many units does it sell per month?

## When to prefer this

Choose this endpoint when you need a single ASIN's current Amazon pricing combined with historical price averages and sales volume estimates in one call, without scraping. Ideal for price-drop alerts, deal validation, FBA product research, and competitive analysis across 11 Amazon marketplaces. Prefer this over a bulk ASIN endpoint when you only need one product at a time and want the lowest per-call cost.

## Known failure modes

- Invalid or non-existent ASIN returns an error or empty result
- Unsupported marketplace domain returns an error
- ASIN exists but has insufficient tracking history — price_history fields may be null or sparse
- Rate limiting or payment failure returns a 402 or 429 response
- Products recently added to Amazon may have no historical data

## How this service works

Amazon price + price history + monthly sales by ASIN. One call, one ASIN: current buy box, Amazon, lowest new and used prices PLUS 30/90/180-day price averages and the typical 180-day price range, estimated monthly sales, sales rank, rating, review count, offer count, brand, category, image. From tracked marketplace history, not a page scrape. 11 Amazon marketplaces (domain=us, uk, de, fr, jp, ca, it, es, in, mx, br). Free sample: /api/sample/product

## Output

A JSON object containing: product title, brand, image URL, Amazon product URL, current prices (buy box, lowest new, lowest used), price history (30/90/180-day averages, typical 180-day low and high, percent vs 90-day average), estimated monthly units sold, sales rank, rating, review count, new offer count, whether Amazon is the seller, currency, marketplace, and data timestamp.
