How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
A JSON object containing: the two-letter country code extracted from the IBAN, a boolean indicating whether the account has been positively verified, a boolean for whether the country is supported, and a boolean confirming whether the checksum and length are valid per IBAN standards.
Example use cases
Pre-transfer IBAN sanity check
“Before I wire money to this supplier, can you validate their IBAN for me: DE89 3704 0044 0532 0130 00 — I want to know if the checksum is correct and whether it's a supported country.”
Bulk onboarding form validation
“A user just filled in their bank IBAN as FR76 3000 6000 0112 3456 7890 189 during signup — can you verify it's correctly formatted and the checksum is valid before we save it?”
Detecting unsupported payment region
“I have a customer in an unusual region with IBAN AE070331234567890123456 — can you check if that country is supported and whether the IBAN itself passes validation?”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/network/iban-validate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, low-cost ($0.001 USDC) programmatic check of any IBAN's structural validity — checksum, length, and country support — prior to initiating a payment or onboarding a bank account. Prefer this over manual regex checks or expensive banking API integrations when you only need format/checksum validation and country identification, not full account existence confirmation.
Side effects
- Malformed or non-IBAN string returns failed validation flags
- IBAN from unsupported country returns supported_country: false
- Network or worker timeout returns no response
- Payment not included or insufficient USDC results in HTTP 402 before validation runs
- IBAN longer than 64 characters rejected at input schema level
