An EU VAT number check — VAT validity, and the VAT registration behind it. Relevant wherever a VAT number is being relied on or cited: the check reads the official VIES service (European Commission), keyless, and returns valid, invalid or unknown — an outage is never reported as invalid — with the member state, the register's own request date, and the trader identity only where that member state discloses it. GB is out of scope after Brexit; XI (Northern Ireland) is covered. Not tax advice.

x402: an unpaid request gets a 402 with the price and pay-to wallet. addrbook never pays.

As the x402 Bazaar reports, from payments Coinbase's facilitator settled. Read 27 Oct 2026, 21:42 UTC. addrbook has not counted these payments itself.

How it asks to be paid

Network	Price	Paid in	Settled by	Pays to

From its own 402 answer at 26 Oct, 22:50 UTC. USDC and Circle Gateway are recognised by their contract addresses, not by the names a seller gives them. How payments are read
