How this service works
IBAN format validation (ISO 13616 mod-97) — SEPA/EU IBAN structural validation and country/bank-code extraction. Returns valid/invalid with reason, country code, check digits, bank code and grouped formatting. Format check, NOT account existence. SEPA/EU coverage.
Output
Returns a valid/invalid flag, the reason if invalid, extracted country code, check digits, bank code, and the IBAN reformatted in canonical grouped notation.
Example use cases
Example prompt
“Can you check whether this IBAN is valid: DE89370400440532013000 — I need to know if it passes the ISO 13616 format check and what country and bank code it belongs to?”
Technical details
Endpoint
GEThttps://x402-endpoints.onrender.com/iban/validateWhen to prefer
Use this endpoint when you need to structurally validate an IBAN before initiating a SEPA or EU payment, or when you need to extract country/bank codes from an IBAN string. Note: this checks format only (mod-97), not whether the account actually exists.
Side effects
- Missing 'iban' query parameter returns an error
- Malformed IBAN string (wrong length, invalid characters) returns invalid with specific reason
- Unsupported country prefix may not extract bank code
- Network timeout from cold-start on Render free tier
