## 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 agents-openwebninja-com-property-zestimate-efdb978d
```

Example prompt: What's the Zillow Zestimate for the property with zpid 28253016? I want to know Zillow's estimated market value before making an offer.

## When to prefer this

Use this endpoint when you need Zillow's proprietary Zestimate for a specific property and already have the zpid or Zillow listing URL. It is the fastest and most direct way to retrieve a single property's estimated market value from Zillow without scraping. Prefer this over general property search endpoints when you know the exact property identifier.

## Known failure modes

- Invalid or missing zpid returns an error status
- Property not found on Zillow (zpid does not exist) returns empty or error response
- Zestimate unavailable for the property (some properties lack estimates) returns null or missing zestimate field
- Malformed URL parameter may cause request failure
- Rate limiting or payment issues may result in 402 or 429 errors
