Look up a building or address in the national register

Retrieve the official record for a building, dwelling or address from a national buildings-and-addresses register: construction year, floor area, use, status, how many units a building contains, and the register identifiers that link an address to the object it designates. The authoritative record as maintained by the responsible authority, as opposed to a listing-site or scraped property description. Dutch BAG (Basisregistratie Adressen en Gebouwen) coverage: adres, pand (bouwjaar, gebruiksdoel, aantal verblijfsobjecten), verblijfsobject (oppervlakte).

price-ascending: candidates are ordered by the listed price of the operation, with no managed-first preference applied. Unlike /v1/apis, this surface does not rank Apiosk-settled listings above federated ones — a comparison that reorders on commercial grounds is not a comparison. Pass sort=managed_first for the catalog's ordering.

PDOK — Dutch Geospatial & Government DataGET /kadaster/bag/ogc/v2/collections/adres/items$0.02via ApioskBAG adres: the address record and the identifiers that link it to an object. No bouwjaar and no oppervlakte — it answers which object an address designates, not what that object is like.
PDOK — Dutch Geospatial & Government DataGET /kadaster/bag/ogc/v2/collections/pand/items$0.02via ApioskBAG pand: the building itself, with bouwjaar, status, gebruiksdoel and the number of units inside it. The offer to pick when the question is about a building.
PDOK — Dutch Geospatial & Government DataGET /kadaster/bag/ogc/v2/collections/verblijfsobject/items$0.02via ApioskBAG verblijfsobject: one dwelling or unit, with oppervlakte in square metres and its main address. The offer to pick when the question is about a home rather than the building containing it.
PDOK — Dutch Geospatial & Government DataGET /lv/bgt/ogc/v1/collections/pand/items$0.02via ApioskBGT pand: a far more precise surveyed outline than the BAG footprint, but none of the register attributes — no bouwjaar, no oppervlakte, no gebruiksdoel. Carries bag_pnd, so it is the geometry half of an answer the BAG offers complete.

Compared: listed price, settlement rail and input compatibility. Not measured yet: latency, reliability, result quality, and provider terms such as rate limits, jurisdiction and licensing.
