When you visit api.openarchieven.nl, you're immediately sent to a different website. That's a red flag for anyone trying to assess whether this API service is legitimate. Most API providers keep their documentation on the same domain and provide clear contact information. Here, the redirect to openarch.nl means you have to trust that second domain instead. The technical security is good, but the lack of identity on this subdomain makes it hard to know who is behind the API. If you're considering using api.openarchieven.nl for your projects, check openarch.nl for proper documentation, privacy policies, and contact details. Without that, it's better to use caution.
