Validate IBANs and look up banks and BIC/SWIFT codes for ERP, invoicing, payroll and AI-agent workflows. Coverage: 89 countries, plus Swiss clearing lookup, SEPA and country-risk indicators, batch validation, payment-reference checks, postal-address checks and Swiss QR-bill checks. REST API and MCP service with 11 tools. Try 25 calls per day without a key; anonymous API keys include 25 calls per month, or 200 after email activation. Paid credit packs and a Pro subscription are available. Batch validation uses one unit per IBAN. Open-source code (MIT). Format and checksum validation does not prove account existence or ownership; this is not beneficiary AML/KYC screening.
IBANforge validates IBANs, provides bank and BIC data, and offers compliance checks via a REST API and SDKs.

IBANforge FAQ
Can I try the API without signing up?+
Yes. No key gives up to 25 validations per week; a free key (no card) provides 200 requests per month.
What does a free key give me?+
It allows access to every endpoint with a limit of 200 requests per month after claiming the key via email.
Are the IBANs I send stored?+
IBANs are checked in memory only; they are not persisted. File audit reports are deleted after payment or after 2-24 hours.
What is the x402 payment method?+
x402 uses HTTP 402 to request USDC payment on Base L2; agents can pay per call without an API key.
What countries provide full national-register verification?+
DE, AT, BE, SK, CZ, BG, CH and LI have full bank-code allocation checks.
Does IBANforge perform AML/KYC on account holders?+
