What is vatnode?

vatnode is an EU VAT number validation API. You send a VAT ID, and vatnode checks it in real time against the official EU VIES system, enriches it with national registry data where available, and returns a clean JSON response with the validity result, company details, VAT rates for that country, and a timestamped audit reference. It's built for developers adding VAT validation to invoicing, checkout, or supplier-onboarding flows.
