Geosapiens API – Essential

This documentation is intended for developers and partners who integrate with or call the Essential API.

The API enables you to submit a location—either as a civic address or geographic coordinates—and receive standardized flood hazard scores, flood risk scores, and a wildfire hazard score for that location.

Designed for speed and ease of integration, the Essential API delivers reliable, property-level risk intelligence to support underwriting, pricing, and risk management workflows.
