Building Profile API

Retrieve commercial building profiles for any U.S. property address including building class, year built, total square footage, floor count, primary tenants, property management, ownership entity, major renovations, parking ratio, and transit access — all from a single API call.

API Overview

This API provides real-time commercial building intelligence for any U.S. property address by aggregating data from commercial real estate listing services, county assessor records, building owner websites, CRE news, and property management firm disclosures. Commercial real estate brokers, tenant representatives, facility service providers, competitive intelligence teams, and leasing professionals use this data to qualify buildings, identify tenant rosters, map ownership structures, and target service sales opportunities across commercial property portfolios.

Building Classification

Identify building class (A, B, or C), year built, total rentable square footage, and floor count to rapidly qualify properties for tenant representation, investment underwriting, or service vendor targeting.

Tenant & Ownership Mapping

Surface notable primary tenants, property management firms, and ownership entities to power competitive intelligence, teaming strategies, and precision outreach to building decision-makers.

Amenity & Access Signals

Capture recent renovations, parking ratio, and transit accessibility to differentiate buildings for tenant site selection, benchmark Class A amenity standards, and support leasing comparables.

Premium API

This is a premium API that utilizes advanced AI analysis across commercial real estate listing services, county assessor records, building owner websites, property management firm disclosures, and CRE publications to provide comprehensive building profiles for any commercial property address.
