## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability latam-datos-api-argentina-cbu-validator-7ac2ba75
```

Example prompt: Can you check whether the Argentine CBU number 2850590940090418135201 is valid, and tell me which bank it belongs to?

## When to prefer this

Use this endpoint when you need to programmatically verify an Argentine CBU before initiating a bank transfer, onboarding a user, or processing a payment. Prefer this over generic format-check libraries because it also resolves the issuing bank code, enabling downstream bank-specific routing logic. Best suited for fintech workflows, accounts-payable automation, and compliance checks targeting the Argentine banking system.

## Known failure modes

- Invalid or malformed CBU string returns valido: false with no banco code
- Missing 'valor' query parameter causes a 400 or error response
- Network timeout if the Render-hosted service is cold-starting
- CBU with correct length but invalid checksum returns valido: false
- Non-Argentine bank account formats not supported
