POST /v1/invoices/counterparty-check

unprobed

Check a known EU VAT ID and/or Peppol participant using separate tax-validity, entity-match, and discoverability evidence. VIES is never used for name search and upstream responses are not resold. / 既知のEU VAT IDまたはPeppol参加者を税番号有効性・法人一致・到達性に分けて確認します。VIESは名称検索に使わず、元データは再販しません。

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
