Preserve what the property is called.
Parcel IDs, UPRNs, REFCATs, titles, cadastral units and official addresses remain source-native underneath the global contract.
PropData turns fragmented cadastral, parcel, address, title, building, transaction and geospatial systems into one governed property intelligence layer—without flattening away the local meaning that makes the data trustworthy.


Scale without semantics is just storage.
THE PROPDATA OPERATING PRINCIPLEParcel IDs, UPRNs, REFCATs, titles, cadastral units and official addresses remain source-native underneath the global contract.
Parcels, buildings, titles, transactions and geometries become deterministic relationships instead of disconnected datasets.
Authority, producer, source system, revision and coverage state stay attached so downstream software can reason about evidence.
When an authority does not publish a fact, PropData returns a truthful null instead of manufacturing confidence.
We do not take one U.S.-centric schema and rename fields country by country. Each product starts from the authoritative identity system and source semantics of that market, then earns its place in the global layer.
Select your country below. Pricing, currency, product depth and coverage are market-specific, while the operating contract stays consistent.
One global property request can begin as an address, coordinate, parcel, UPRN, REFCAT or title. PropData resolves that input into native identity first, then attaches only the relationships and intelligence the source contract supports.
Address · parcel · UPRN · REFCAT · title
Boundary · building · containment · geometry
Assessor · title · use · transaction
Valuation · comps · rent · market · risk
Authority · producer · dataset · revision
Match · availability · truthful nulls
REST · MCP · bulk · custom
Coverage is a contract, not a marketing claim.
There is no universal cadastral schema hiding behind the world’s borders. A UPRN is not a referencia catastral. A French parcel is not an Australian legal block. We expose the common operating layer without erasing the native systems that determine what every field actually means.
The right abstraction is not “every country has every field.” It is a consistent contract for discovering what identity and layers are actually available in that jurisdiction.

“Source-dependent,” “promotion-governed” and “certifying” are intentional product states. They prevent a valid identity match from being misrepresented as universal enrichment coverage.
Country-native property truth should not be trapped in country-specific downloads. PropData turns it into production infrastructure with credentials, response contracts and delivery shapes built for modern applications and agents.
// Same operating contract. Native country identity underneath. const url = new URL( 'https://propdata-api-worker.sales-fd3.workers.dev/v1/property' ) url.searchParams.set('country', marketCode) url.searchParams.set('address', inputAddress) const response = await fetch(url, { headers: { 'x-api-key': process.env.PROPDATA_API_KEY } }) const property = await response.json() // Identity, coverage and provenance are independent signals. // Missing country layers are never inferred from another market.

Use one commercial relationship for country-native property intelligence, bulk delivery, AI-native access, white-label infrastructure, custom response contracts and new-market sourcing. Individual markets remain self-serve; multi-country and unusual-volume workflows are scoped around the production contract you actually need.
