What you get

Postcode + number

The Dutch way round: two fields in, a complete address out. No free-text parsing, no guessing.

Nightly BAG sync

Built from the official BAG extract. New builds appear within a day of registration, demolitions disappear the same way.

Suffix handling

Letters and additions (62-H, 3 bis) resolved against the register instead of being stripped.

Bulk endpoint

Up to 5 000 lookups per request, answered in a single round trip. Ideal for cleaning an existing customer table.

Reverse lookup

Give a BAG identifier, get the address. Useful when you already store the id and need to render it.

Plain HTTP

No SDK required. A bearer token, a query string and JSON back. Everything is idempotent and cacheable.
