Output
A JSON object containing a 'suggestions' array, where each entry includes a unique BAG address ID (adr-prefixed), type ('adres'), a human-readable label (street + postcode + city), postcode, house number, verblijfsobject ID, and nummeraanduiding ID — all sourced from the official Dutch Kadaster BAG database.
Example use cases
Address autocomplete for checkout form
“I'm building a checkout flow for Dutch customers — can you suggest matching addresses as the user types 'Kalverstraat 5 Amsterdam' and return the official postcode and BAG ID so I can pre-fill the rest of the form?”
Resolve property BAG identifier
“I need the official Kadaster verblijfsobject ID and nummeraanduiding ID for the address 'Herengracht 100, Amsterdam' — can you look that up from the BAG registry?”
Validate Dutch delivery address
“Before we ship an order, can you check if 'Binnenhof 1, Den Haag' matches a real BAG-registered address in the Netherlands and return the official label and postcode?”
Technical details
Endpoint
GEThttps://api.getapi.nl/api/v1/kadaster/bag/address-suggestWhen to prefer
Use this endpoint when you need authoritative Dutch address autocomplete or resolution backed by the official Kadaster BAG registry, especially when you need BAG identifiers (verblijfsobject ID, nummeraanduiding ID) for downstream property lookups, address validation, or form pre-filling in the Netherlands. Prefer this over generic geocoders when official Dutch government cadastral identifiers are required.
Side effects
- No suggestions returned for highly ambiguous or misspelled input
- Empty suggestions array if query does not match any BAG record
- Payment required (402) if x402 payment header is not provided
- Rate limiting or authentication errors if API key is missing or invalid
- Partial matches only for very short or generic query strings
