How to call it
A starting template for Dutch Customer Data API. Replace ENDPOINT with the path from the official documentation, which we link above rather than guess at.
# Authentication requirement is unconfirmed. Check the documentation before relying on this.
curl -s "https://free.bedrijfsdata.nl/ENDPOINT" \
-H "Authorization: Bearer YOUR_TOKEN" \
-H "Accept: application/json"This API does not send CORS headers, so a browser will block a direct call from your front end. Call it from your server, or put a small proxy in front of it.

Dutch Customer Data API — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Dutch Customer Data API free to use?
Dutch Customer Data API is listed in our free catalogue, but it requires some form of authentication, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.
Does Dutch Customer Data API need an API key?
Dutch Customer Data API requires some form of authentication. Check the provider's documentation for which scheme it expects.
Can I call Dutch Customer Data API from browser JavaScript?
Not directly. Dutch Customer Data API did not return CORS headers when we checked, so the browser will block your page from reading the response even though the request itself succeeds. Call it from a server, or put a small proxy in front of it.
Is Dutch Customer Data API still working?
Not at our last check on 2026-09-18. Dutch Customer Data API did not respond successfully, which is why it is marked as down here. This may be temporary; we re-check on a schedule and the badge above reflects the most recent run.
Is Dutch Customer Data API available over HTTPS?
Yes. Dutch Customer Data API serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
