Look up a building or address in the national register
Retrieve an official BAG address and building record including postcode, street, municipality, province, WGS84 and RD coordinates, building identifiers, year, area, status and use purpose.
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.
| Provider | Operation | Price | Settlement | Notes |
|---|---|---|---|---|
| PDOK Maps & Addresses | GET /kadaster/bag/ogc/v2/collections/adres/items | $0.02 | via Apiosk | BAG 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. Does not accept: bag_id. |
| PDOK Maps & Addresses | GET /kadaster/bag/ogc/v2/collections/pand/items | $0.02 | via Apiosk | BAG pand: the building footprint itself, with construction year and lifecycle status. It does not carry registered use; choose the BAG verblijfsobject offer when the question asks for gebruiksdoel at an address. Does not accept: bag_id. |
| PDOK Maps & Addresses | GET /kadaster/bag/ogc/v2/collections/verblijfsobject/items | $0.02 | via Apiosk | BAG verblijfsobject: the registered usable unit at an address, with gebruiksdoel, floor area, status and its building link. Prefer this offer when the question asks what an address is registered for. Does not accept: bag_id. |
| PDOK Maps & Addresses | GET /lv/bgt/ogc/v1/collections/pand/items | $0.02 | via Apiosk | BGT 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. Does not accept: bag_id. |
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.
