How this service works
The OpenRouter for AI-agent tools: one gateway, one wallet, every capability. Built-in tools, forged tools, a global verified business directory and 2,000+ aggregated x402 services, all paid per call in USDC via x402 (HTTP 402). No signup, no API key.
Output
Returns a JSON object with an 'ok' boolean field indicating whether the CLABE is valid. A true value means the CLABE passed format checks (18 digits) and the Luhn-style check digit verification. A false value indicates the number is invalid.
Example use cases
Pre-payment CLABE verification
“Before I send a wire transfer to this Mexican bank account, can you validate the CLABE 032180000118359719 to make sure it's a legitimate number and won't get rejected?”
Batch onboarding form validation
“A user just entered 014680524557898745 as their CLABE on our onboarding form — can you check whether that's a valid CLABE number before we save it?”
Payroll disbursement check
“I need to pay a Mexican contractor and their CLABE on file is 706180001200004635 — can you verify it's properly formatted with a valid check digit so I can proceed with the payroll run?”
Technical details
Endpoint
POSThttps://toll402.dev/v1/t/clabe_validateWhen to prefer
Use this endpoint when you need a fast, cheap, offline CLABE validation without setting up any authentication or API keys. It is ideal for pre-validating Mexican bank account numbers before financial transactions, form submissions, or data ingestion pipelines. At $0.001 USDC per call with no signup required, it suits high-volume validation scenarios where accuracy and speed matter more than network-based bank verification.
Side effects
- Invalid or malformed CLABE returns ok: false
- Non-numeric characters beyond allowed spaces/dashes cause validation failure
- CLABE shorter or longer than 18 digits returns ok: false
- Network or gateway errors return HTTP error codes
- Payment failure returns HTTP 402 if USDC wallet is insufficient
