VAT numbers
Check a VAT number in VIES, the EU's register. With business_id, the check names that business as requester: VIES issues a consultation number, the evidence that this seller confirmed the number, its name and address before treating the buyer as a business. The answer is reused for that seller for 24 hours. Without it, the answer is the number's validity, shared across sellers: reused for 24 hours when verified, an hour when not, two minutes when VIES did not answer. A number outside the EU, Northern Ireland's XI included, answers unavailable with UNSUPPORTED_COUNTRY.

Path Parameters
The VAT number with its country prefix: FI01120389, EL094014201 for Greece. Spaces, dots and dashes are ignored.
Query Parameters
The seller asking. VIES records the business's own EU VAT number as requester and issues a consultation number for it. Without it, or for a business without an EU VAT number, the answer is the number's validity alone, with no consultation number.
