Dutch government data via one API. 10 endpoints, one key, 1 000 free calls per month.
Omnizoek aggregates Dutch government and public data sources — BAG addresses, VIES VAT numbers, RDW vehicle data, EP-Online energy labels, NS train disruptions and more — behind a single REST API with one API key.
No SDK required. Send a plain GET request, get back structured JSON. GDPR-compliant by architecture, in-process caching included.
Each endpoint is fully documented, cached, and available via a simple GET request. Integrate in minutes — no SDK needed.
