How this service works
309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.
Output
Returns a JSON object with an `ok` boolean indicating whether the request succeeded and a `paid` boolean confirming payment was processed; the IBAN validation result (valid/invalid) is embedded in the response body.
Example use cases
Pre-payment IBAN verification
“Before I send this wire transfer, can you confirm that GB29NWBK60161331926819 is a valid IBAN so I don't lose the money?”
Form validation for bank onboarding
“I need to verify that the IBAN a new customer entered — FR7614508059201765587534 — is correctly formatted before I let them proceed with onboarding.”
Bulk supplier payment data cleanup
“Can you check whether this supplier's IBAN NL91ABNA0417164300 is valid before I add it to our payment batch?”
Technical details
Endpoint
GEThttps://x402-toolbox.shablony-pro.workers.dev/util/iban-validator?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call IBAN validation with no API key or signup required — ideal for AI agents that need to validate bank account numbers on demand using x402 micropayments. Prefer this over building custom IBAN checksum logic or subscribing to a larger banking data service when you only need structural/checksum validation.
Side effects
- Malformed or missing IBAN input returns validation failure
- Non-IBAN string passed as input may return ok:false or an error
- Payment failure (insufficient USDC balance) returns HTTP 402 and validation is not performed
- Unsupported IBAN country code may return invalid even for structurally plausible strings
