Check a web shop BEFORE paying it: is the shop on this domain a real, active, registered company in a European business register, and does the domain belong to that company? Reads the registration / VAT number the shop states on its own imprint, terms or footer, looks it up in the national register (Denmark, Sweden, Norway, Finland, UK, Germany and other EU countries), validates VAT in VIES/HMRC, screens the company against sanctions lists, and checks domain age, TLS certificate and a public phishing list. Returns match = verified | partial | not_found | attention with evidence per signal and the source of each field. Evidence, not a verdict — you decide. Pass vat_number (and country) from the checkout or invoice when you have it; it also catches a checkout VAT number that belongs to a different or ceased company. When the free monthly lookups run out, the result contains buy_url: show it to your user — one payment adds 150 lookups.
The shop's domain or URL, e.g. "example-shop.dk"
ISO country code of that number, e.g. "dk", "se", "uk" — helps read a bare number
VAT or company registration number shown at checkout / on the invoice, e.g. "DK27528430" or "556710-4699"
Company name shown at checkout, if any
