Property Data API v4 Documentation

Getting Started

Deprecation of the Estated API documentation: We are in the process of migrating components of the Estated API architecture to ATTOM infrastructure. This transition will ensure the long-term stability and reliability of the platform. Your existing API keys will remain valid, and no changes will be required to your integration. Additionally, no downtime is expected during this migration.

As part of this process, we want to prepare you for an important upcoming change: the Estated documentation will be deprecated at some point in 2026. While no specific date has been set, the current Estated documentation will no longer be maintained or accessible after deprecation. Updated documentation and resources will be available through ATTOM moving forward. If you notice any issues, please visit https://www.attomdata.com/contact-us/.

Welcome to the documentation. We have created a simple, easy to use API and have done our best to document each feature here.

All API calls must include a valid API key, this is our way of identifying you and authorizing your call.
