What this source cannot tell you

⚠ Anything outside Worldwide. A request past that edge comes back empty rather than approximated.
⚠ Which years it spans, because the covered period is not declared.
⚠ Anything OpenStreetMap Nominatim does not publish. ParcelOps returns this source as it stands and never fills a blank field from a different one.
⚠ Open-map address context is not a legal cadastral or ownership record.

⚠ Open-map address matches require confirmation before they are used as legal parcel identity.
⚠ A miss returns records: [] with a caveat naming a cause you can act on, not a bare empty result.
⚠ When a query carries a postcode and matches nothing, one retry runs without it; that answer says so in a caveat and is not postcode-verified.
