How this service works
Pay-per-call tools for AI agents: web search + content, documents, live market data, and multi-chain wallet/gas reads. Mainnet test from $0.000001 USDC on Base. Pay-per-call tools for AI agents in USDC on Base (x402/MPP): search, pdf, web-read, extract, summarize, fact-check, translate, jobs, discover. See GET /capabilities.
Output
Returns a validation result indicating whether the IBAN passes the ISO 13616 mod-97 checksum, and if a BIC was provided, whether it conforms to ISO 9362 format. Typically includes a boolean pass/fail, the parsed IBAN components (country code, check digits, BBAN), and any error details if validation fails.
Example use cases
Pre-transfer IBAN sanity check
“Before I wire money to this supplier, validate their IBAN DE89370400440532013000 to make sure it passes the checksum — I don't want the payment to bounce.”
Payroll system account verification
“We're onboarding a new employee in France with IBAN FR7630006000011234567890189 and BIC BNPAFRPP — can you verify both are valid before I add them to payroll?”
Fintech form input validation
“A user just entered IBAN NL91ABNA0417164300 on our checkout form — run a quick checksum validation so I know whether to show them an error message.”

Endpoint
GEThttps://x402.agentindex.world/validate/iban?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, standards-compliant mod-97 checksum validation of an IBAN before initiating a payment or storing bank account details. Prefer this over client-side regex checks because it implements the full ISO 13616 algorithm. Also ideal when you need to simultaneously verify a BIC code in a single call without standing up your own banking validation library.
Side effects
- IBAN string contains spaces or hyphens not stripped — may return invalid when the number is actually correct
- BIC provided but IBAN country mismatch — may flag BIC as invalid
- Malformed IBAN shorter than minimum length — returns validation error
- Non-alphanumeric characters in IBAN cause parse failure
- Empty or null IBAN field returns 422 or bad request
