EU VAT number check: format and checksum are tested locally first (a malformed number is rejected with HTTP 400 and no charge), then the official VIES service answers whether it is valid, with the registered name and address where the member state discloses them. All 27 EU states plus Northern Ireland (XI). Source: European Commission VIES.

On-chain payments
Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes — watching since 2026-10-10; earlier history is still being backfilled, so these figures cover 1 day, not 30. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 10 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
