Ask Mago whether a VAT number is real and it asks the European Commission for you — no tab switching, no copy-pasting into a government form that times out.
NL999999999B01 — worth checking before you apply the reverse charge.The VIES web form is slow, rate-limited and logs you out. Mago talks to the same register over its API, in the screen where you were already working.
A valid number is only half the check. VIES returns the registered company name and address, so you can see whether the number actually belongs to the customer who gave it to you.
This skill never writes to your store. There is no confirm step because there is nothing to confirm.
Requires Mago Core. No API key, no account — VIES is a free public register.
