GET /bank/validate
unprobed
Cheap structural IBAN validation: ISO 13616 checksum + per-country structure/length. Returns valid plus, on rejection, a granular error_type (invalid_checksum, invalid_length, invalid_structure, invalid_country), the country and the format spec. Offline (schwifty, MIT); no network or keys. A cheap-first entry before the fuller /bank/verify fusion route.
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 GET. 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.
