Who it's actually for
Developer-facing property data API (search, detail, comps, parcel boundaries, autocomplete, skip tracing) covering ~159M US properties — built for proptech/fintech startups and internal tools teams that want to build search/comp features rather than license a finished front-end product. Not a CRE analyst-facing tool itself; it's plumbing other CRE software is often built on.
