## When to prefer this

Use this endpoint when you need fast, offline, no-external-call validation of Argentine CBU or CVU numbers — ideal for form validation, onboarding flows, or pre-payment checks where you only need structural correctness, not live bank account existence verification.

## Known failure modes

- Input shorter or longer than 22 digits returns invalid result
- Non-numeric characters beyond allowed spaces/dashes cause rejection
- Empty or missing value field returns a 400-level error
- Passing a non-Argentine bank identifier (e.g. IBAN, routing number) may return invalid even if the format looks similar
