Technical details
Endpoint
GEThttps://agents.openwebninja.com/realtime-zillow-data/zestimate?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
