## 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-amazon-price-drops-deals-feed-280f4b3e
```

Example prompt: Find me Amazon US deals from today where the price dropped by at least 20%, the seller is Amazon itself, and the product is at its lowest price ever — return up to 150 results.

## When to prefer this

Use this endpoint when you need a paginated feed of recently price-dropped Amazon products across any of 11 marketplaces, with rich filtering (category, discount %, price range, seller type, rating, lowest-ever). It is ideal for deal-finding bots, price alert systems, retail arbitrage sourcing tools, and affiliate deal newsletters. Prefer it over the price history endpoint when you want a broad feed of deals rather than deep history on specific ASINs.

## Known failure modes

- Invalid or malformed selection JSON returns an error or empty deals array
- Unsupported marketplace domain code returns an error
- No deals matching the filters returns an empty dr array
- Overly restrictive filter combination (e.g., very high minimum discount with lowest-ever flag) yields zero results
- Rate limiting or payment failure returns a 402 or 429 error

## How this service works

Amazon price drops and deals feed. Products whose price just dropped (or sales rank changed), with filters for category, minimum discount, price range, rating, Amazon as seller, lowest price ever and more. Up to 150 deals per page. For deal finding, price alerts and sourcing.

## Output

A JSON object containing a deals array (dr) where each item includes the ASIN, product title, current price in cents, absolute price delta, and delta percent. Also includes matched category IDs and names, plus metadata showing the marketplace domain ID, whether the response was cached, and the price paid per call.
