How this service works
Use when an agent needs IBAN validation before saving bank details, invoicing or a payout: structure, mod-97 and national BBAN checksum where defined, plus country, bank code, account code, bank name, BIC and SEPA membership. Offline registry, instant. Checks structure, not whether the account exists. $0.01 USDC on Base; charged only on 2xx, never for invalid input.
Output
Returns a validation result indicating whether the IBAN passes structural, mod-97, and national BBAN checksum checks, along with parsed fields: country code, bank code, account code, bank name, BIC, and SEPA membership status. Sourced from an offline registry for instant response.
Example use cases
Pre-payment IBAN validation
“Before I send this supplier payment, can you validate the IBAN DE89370400440532013000 and confirm the bank name and BIC so I know it's correct?”
Invoice payout verification
“We're about to run payouts — can you check if FR7630006000011234567890189 is a valid IBAN, which bank it belongs to, and whether it supports SEPA transfers?”
Customer bank account onboarding
“A new customer submitted the IBAN NL91ABNA0417164300 during signup — can you validate it and return the bank details so we can confirm it before saving?”
Technical details
Endpoint
POSThttps://api.facts402.com/iban?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need instant, offline IBAN validation with enriched bank metadata (BIC, bank name, SEPA status) at very low cost ($0.01/call). Ideal for payment pipelines, invoicing systems, and payout agents that need to pre-validate recipient bank details before executing transfers. Prefer this over live banking APIs when you need speed and reliability without round-trips to external banking infrastructure.
Side effects
- Invalid IBAN format or characters (fails pattern match, 400 error)
- IBAN fails mod-97 checksum validation (returns invalid status)
- Country not recognized or BBAN checksum not defined for that country (partial validation)
- IBAN too short or too long (rejected by schema pattern)
- No bank registry entry found for given bank code (bank name/BIC may be absent)
