## 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 ebay-products-by-category-search-7348a6b5
```

Example prompt: Search eBay's Electronics category (category_id 9355) for used laptops under $800, sorted by lowest price, buy-it-now only, on the first page — show me real-time listings with prices and seller ratings.

## When to prefer this

Use this endpoint when you need real-time eBay product listings scoped to a specific category, with rich filtering by price range, condition, buying format (auction/buy-it-now/offers), and sorting. Prefer this over generic web scraping when you need structured seller data, feedback scores, and shipping info from eBay specifically. Best for price comparison, inventory research, or building eBay-focused shopping agents.

## Known failure modes

- Missing or invalid category_id returns an error or empty result set
- Invalid sort_by enum value causes a validation error
- Page number out of range (>100) returns validation error
- Non-existent eBay category ID returns empty product list
- Invalid domain value may return no results or error
- Price filter min_price greater than max_price may yield no results
