Output
Returns a JSON object indicating whether the KVK number is valid and found, whether the business is currently active, the legal form (e.g. BV), a list of business activities with SBI codes, registration start date, postal region code, insolvency status and description, and the member state (NL).
Example use cases
Vendor onboarding compliance check
“We're onboarding a new Dutch supplier and they gave us KVK number 12345678 — can you check if it's valid, active, and what their legal business form is?”
Detecting insolvent counterparties
“Before we sign this contract with a Dutch company, can you verify KVK number 87654321 and confirm they're not in insolvency proceedings?”
Automated invoice KVK verification
“This invoice came in with KVK number 59581883 listed — please check if that number is real and the business is currently active so we can approve payment.”
Technical details
Endpoint
POSThttps://api.getapi.nl/api/v1/validate/kvkWhen to prefer
Use this endpoint when you need to verify Dutch business registrations specifically via KVK number. It is purpose-built for the Netherlands Chamber of Commerce registry and returns structured business metadata including legal form, insolvency status, and SBI activity codes — making it superior to generic company lookup APIs for Dutch B2B due diligence, supplier onboarding, invoice validation, or compliance workflows.
Side effects
- KVK number not found in registry — found: false, valid: false
- KVK number format invalid — error returned
- Company exists but is no longer active — actief: false
- Rate limiting — retry_after field populated
- Network or upstream registry unavailability
