## 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 macaroon-network-iban-validate-55fa7801 -d '<json body>'
```

Example prompt: Can you check whether this IBAN is valid: GB29NWBK60161331926819?

## When to prefer this

Choose this endpoint when you need fast, free-standing IBAN structural and checksum validation with no network dependency on proprietary bank data, no third-party licence, and no latency from live lookups. Ideal for pre-flight checks before payment processing, form validation at onboarding, or offline batch screening.

## Known failure modes

- Malformed or missing IBAN input returns validation error
- Unrecognized country code prefix not in SWIFT registry may return unknown-country error
- Non-alphanumeric characters in IBAN string cause parse failure
- IBAN with correct checksum but wrong country length flagged as invalid

## How this service works

Offline International Bank Account Number (IBAN) structural and checksum validation (ISO 7064 MOD 97-10) against the published SWIFT IBAN Registry per-country length table. Pure algorithmic validation of a published international standard -- no proprietary bank dataset, no network call, no third-party licence dependency.

## Output

Returns whether the IBAN is structurally valid: checksum passes ISO 7064 MOD 97-10, and the string length matches the SWIFT IBAN Registry for the detected country code. No live bank data is queried — purely algorithmic.
