agosint vat
EU VAT number validation against the official VIES service: valid or invalid, the registered name and address where the member state discloses them, and a consultation number when you give your own VAT number. Each check is made for the buyer, never cached. Signed answer; nothing is charged when the service is unavailable.

On-chain payments
Peak day 2026-10-05: 69 payments. Last indexed day 2026-10-13: 23. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 4 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
last 7 probes, oldest → newest · 100% pass · re-probed on its probe tier's interval (next_check_by on the record) from nohumans infrastructure — never self-reported
