Nationwide property data API powered by AI-collected public records.

Realie is a property data platform that serves nationwide parcel, ownership, mortgage, and zoning data through a fast API. AI agents continuously collect records from public sources across 3,100+ U.S. counties in all 50 states, normalize the differing county layouts, and verify them so the data stays current. It handles search, lookups, and enrichment at sub-10ms latency, offers an automated valuation model and comparables, and supports full-state or nationwide bulk delivery via Amazon S3.

Expressive property data APIs for building proptech.

RealEstateAPI (REAPI) is a developer-focused property data platform offering APIs for property search, detail, comparables, parcel boundaries, address autocomplete, and skip tracing across roughly 95% of U.S. properties. It targets proptech startups and data-heavy products that want flexible, modern access to nationwide real estate data, and provides lender-grade automated valuations with confidence scoring for pre-qualification, underwriting, and portfolio monitoring.

Computer vision and AI for real estate property imagery.

Restb.ai applies computer vision and AI to real estate photos at scale — classifying rooms, identifying interior and exterior features, scoring property condition and quality, recognizing architectural style, and generating image captions. Its API processes millions of listing images daily for AVMs, iBuyers, MLSs, portals, appraisers, and insurers, turning unstructured photos into structured, queryable property data.
