How this service works
x402-Werkzeuge für autonome Agenten.
Output
A JSON object containing: whether the IBAN is valid, the checksum validity flag, SEPA eligibility, the formatted IBAN, the raw BBAN, parsed BBAN components (bank code, account number), country code, expected and actual length, a list of any issues found, a note clarifying that existence of the account is not verified, and BIC details (if present or derivable) including branch, country, location, primary-office status, format validity, and whether the BIC matches the IBAN.
Example use cases
Validate supplier bank details before payment
“Before I wire money to this supplier, can you check if their IBAN DE89 3704 0044 0532 0130 00 is valid and whether the BIC COBADEFFXXX actually matches it?”
SEPA eligibility check for recurring direct debit
“I need to set up a SEPA direct debit for a customer — can you verify that the IBAN GB29 NWBK 6016 1331 9268 19 is valid and SEPA-eligible?”
Onboarding form IBAN validation
“A new user just entered their bank account as NL91 ABNA 0417 1643 00 during signup — can you validate that IBAN and tell me if there are any format issues I should flag to them?”
Technical details
Endpoint
POSThttps://tools.netzhandwerker.de/v1/iban/checkWhen to prefer
Use this endpoint when you need a fast, cheap, formal IBAN validation with BIC matching and SEPA eligibility checks — particularly useful in payment automation, onboarding flows, or supplier management pipelines where you want to catch formatting and checksum errors before initiating a real transfer. Note that it performs formal/structural validation only and does not verify whether the account actually exists at the bank.
Side effects
- Malformed IBAN input that cannot be parsed returns valid=false with issues array populated
- IBAN from a country not in the SEPA register returns country_in_register=false
- BIC provided does not match the IBAN's bank code, returning bic_matches_iban=false
- IBAN with incorrect checksum returns checksum_valid=false
- Payment fails if USDC balance is insufficient for the $0.001 x402 fee
- Network timeout or service unavailability returns an HTTP error
