## 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 zillow-zestimate-lookup-by-zpid-319836da
```

Example prompt: What's the Zillow Zestimate for the property with zpid 2089611893? I want to know the estimated market value Zillow has on it.

## When to prefer this

Use this endpoint when you have a Zillow property ID (zpid) and need the current Zestimate for that specific property. Prefer this over general property search endpoints when the zpid is already known. Ideal for real estate agents, homebuyers, or investment tools that need automated programmatic access to Zillow valuations without scraping.

## Known failure modes

- Missing or invalid zpid returns an error response
- Zillow does not have a Zestimate for every property — some properties return null or no estimate
- Rate limiting or upstream Zillow API unavailability may cause failures
- Malformed zpid (non-numeric or incorrect format) may return an error
