## 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 openweb-ninja-zillow-polygon-real-estate-search-e8f63978
```

Example prompt: Search Zillow for homes for sale within the polygon boundary of the Boerum Hill neighborhood in Brooklyn — use the polygon coordinates that outline that specific district.

## When to prefer this

Use this endpoint when you need to search Zillow listings constrained to a custom geographic polygon — ideal for neighborhood boundaries, school districts, opportunity zones, or any irregular geographic area where a simple radius or bounding box search is insufficient. No API key or account required; pay $0.003 USDC per call via x402.

## Known failure modes

- Invalid or malformed polygon coordinates return an error
- Polygon covering no listings returns empty results
- Overly large polygon may time out or return truncated results
- Payment failure via x402 results in 402 response with no data
- Unsupported polygon format or coordinate system causes rejection
