GET /v1/util/iban

unprobed

Validates one IBAN offline: country, expected length, ISO 7064 mod-97 check digits, whether it is inside SEPA, and the account number split out. Deterministic, no network call and no third party that can go down. Built for cleaning a list of accounts one at a time.

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

Try it (unpaid: shows the 402)

curl -si -X GET 'https://flat-rate-llm.kikoribera03.workers.dev/v1/util/iban' -H 'accept: application/json'

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.
