How this service works

Pay-per-call APIs for AI agents — x402 protocol, USDC on Base, no account needed.

Output

Returns whether the IBAN passes the mod-97 checksum validation, the country code extracted from the IBAN (e.g. 'FR'), and the French bank code (code banque) parsed from the IBAN structure.

Example use cases

Supplier payment IBAN check

“Before we wire the invoice payment, can you validate this IBAN for our French supplier: FR7614508711000008565478A93 — I need to know if it passes the checksum and what bank code it maps to?”

Payroll onboarding bank verification

“A new employee submitted FR7610011000201234567890188 as their bank account — can you verify that IBAN is valid and extract the French bank code from it?”

E-commerce checkout IBAN validation

“A customer just entered FR7630004000031234567890143 as their SEPA payment IBAN — is it a valid French IBAN and what bank does it come from?”

Endpoint

When to prefer

Choose this endpoint when you need to validate a French IBAN specifically — it not only checks the universal mod-97 checksum but also parses out the French-specific bank code (code banque), making it more useful than a generic IBAN validator for French banking contexts. It is pay-per-call with no account setup required, ideal for agent workflows needing occasional IBAN verification without a full banking API integration.

Side effects

Missing or empty IBAN query parameter returns an error
Non-French IBANs may validate the checksum but may not return a French bank code
Malformed IBAN string (wrong length or illegal characters) returns validation failure
Network or upstream service error returns HTTP 5xx
