Stanza VAT Validator — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Stanza VAT Validator free to use?
Stanza VAT Validator is listed in our free catalogue, but it requires an API key, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.
Does Stanza VAT Validator need an API key?
Yes. Stanza VAT Validator authenticates with an API key. Keep it server-side rather than in browser code, because anything in your frontend bundle is readable by anyone who opens developer tools.
Can I call Stanza VAT Validator from browser JavaScript?
Not directly. Stanza VAT Validator 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 Stanza VAT Validator still working?
Yes, as of 2026-09-27. Our automated check reached Stanza VAT Validator and recorded a 100% reliability score with a median response time of 290 ms. We re-check on a schedule, and this page updates with the result.
Is Stanza VAT Validator available over HTTPS?
Yes. Stanza VAT Validator serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
