## 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-realtime-product-search-api-openwebninja-x402-9b9c91d2

Example prompt: Search eBay for a used iPhone 14 Pro under $600, sorted by lowest price, buy-it-now only — show me the first page of results from ebay.com.

## When to prefer this

Use this endpoint when you need real-time eBay marketplace data including current pricing, seller information, auction details, and listing conditions. Prefer this over static datasets when freshness matters — e.g., for price tracking, deal finding, or competitive analysis on eBay specifically. Best for structured product searches with filtering by price, condition, buying format, and sort order.

- Invalid sort_by enum value rejected
- Page number out of range (1-100) returns error
