## 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-real-time-property-search-by-polygon-99f0a1bf
```

Example prompt: Search Zillow for all homes currently listed for sale within the polygon bounded by these coordinates in Austin, TX — I want real-time listings with prices and addresses.

## When to prefer this

Choose this endpoint when you need to search Zillow listings within a custom-shaped geographic boundary (polygon) rather than a simple radius or city-level search. Ideal for school district boundaries, neighborhood outlines, investment zones, or any irregular geographic area. No API key or account required — pay $0.003 USDC per call via x402 on Base, Polygon, or Arbitrum.

## Known failure modes

- Invalid or malformed polygon coordinates return an error
- Polygon area too large may return no results or timeout
- No listings found within the specified polygon returns empty results
- Payment failure over x402 prevents access to the endpoint
- Rate limits or temporary Zillow data unavailability may cause errors
