BAG API Kadaster (BYOK) lets an AI assistant read your own BAG API Kadaster data through the BAG API Kadaster API with a key you supply (BAG API key). Read-only: 9 tools (search_addresses, get_address, get_addressable_object, search_addressable_objects_in_bbox, get_dwelling, list_dwellings_in_building, get_building, get_public_space, get_residence_place). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.bag.kadaster.nl. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by BAG API Kadaster. BAG API Kadaster and its logos are trademarks of their owners and are used only to say which service the connector works with.
Sources: Live from the BAG API Kadaster API (api.bag.kadaster.nl) with a BYOK key; documentation: https://github.com/lvbag/BAG-API/blob/master/Getting%20started.md. Endpoints checked against that documentation on 2026-10-16.
