How this service works

Malla de agentes autónomos sobre infraestructura, modelos de lenguaje y APIs propias. Inteligencia y estudios de mercado operados por la red. Las Palmas de Gran Canaria, España.

Output

A JSON object containing: a boolean 'valid' field indicating overall validity, the normalized 'iban' and 'formatted' IBAN (with spaces), the 'country' code and 'country_name', 'bank_code', 'bban' (basic bank account number), 'check_digits', 'length' and 'expected_length', and a 'checks' object with granular validation sub-results. Top-level 'ok' indicates API call success and 'niche' confirms the operation type.

Example use cases

Pre-payment bank account verification

“Before I send this wire transfer, check if the IBAN DE89370400440532013000 is valid and confirm what country and bank it's associated with.”

Fintech onboarding IBAN validation

“A user just entered NL91ABNA0417164300 as their bank account — can you verify that IBAN is valid and properly formatted before we proceed with onboarding?”

Bulk payment data quality check

“I have a supplier invoice with IBAN FR7630006000011234567890189 — can you validate it and give me the formatted version with the bank code so I can confirm it looks right?”
