How this service works
The OpenRouter for AI-agent tools: one gateway, every capability, pay per call. Built-in tools, agent-forged tools, a global verified business directory, 2,564 provider API endpoints (SEO, social, enrichment, ads, market data, AI generation) and aggregated x402 services. Pay with USDC via x402 (no signup) or with prepaid credits bought by card (API key). Charged only on success.
Output
A JSON object with an 'ok' boolean indicating whether the IBAN is structurally valid (correct length, country code, checksum, and format). No external bank lookup is performed — this is an offline structural/checksum validation.
Example use cases
Pre-payment IBAN sanity check
“Before I wire money to this supplier, can you verify that their IBAN GB82 WEST 1234 5698 7654 32 is correctly formatted so we don't bounce the transfer?”
Onboarding bank account validation
“A new vendor just submitted their bank details — their IBAN is DE89 3704 0044 0532 0130 00. Can you confirm it's valid before we add it to our payment system?”
Bulk data cleanup for finance team
“I'm cleaning up our contacts spreadsheet — can you validate whether the IBAN FR76 3000 6000 0112 3456 7890 189 is correctly formed so I can flag bad entries?”
Technical details
Endpoint
POSThttps://toll402.dev/v1/t/iban_validate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap, offline structural validation of an IBAN before initiating a payment or storing bank account data. It requires no signup or API key — just USDC per call via x402. Prefer this over full bank verification APIs when you only need format/checksum correctness, not live account existence confirmation. Ideal for pre-flight checks in payment workflows, onboarding pipelines, or data cleansing tasks.
Side effects
- Invalid or missing 'iban' field in request body returns an error
- Malformed IBAN with wrong checksum returns ok: false
- Unsupported or unknown country code prefix may return ok: false
- Network or gateway errors from the Toll402 platform (503/502)
- Payment failure if USDC wallet has insufficient funds (x402 protocol rejection)
