PAID $0.001 (x402, USDC on Base). Validate an IBAN: give {iban} and get ISO 13616 length + mod-97 checksum validation, the country, the human-formatted grouping, and the bank identifier (e.g. German Bankleitzahl, UK bank code + sort code) extracted from the BBAN where derivable. Pure-offline. Without payment returns the x402 challenge.
