## 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 agentsvc-io-iban-validator-9fd5e54b -d '<json body>'
```

Example prompt: Can you check if DE89370400440532013000 is a valid IBAN and tell me which bank it belongs to and whether it supports SEPA?

## When to prefer this

Use this endpoint when you need to validate a European or international IBAN before processing a payment, onboarding a supplier, or storing bank account data. It combines format validation with live bank lookup (name, BIC, city) and SEPA eligibility in one call. Prefer it over manual regex checks when you also need enriched bank metadata. At $0.002/call with no API key required, it's ideal for lightweight per-transaction validation in automated workflows.

## Known failure modes

- Invalid IBAN format returns valid:false with no bank data
- Unknown or unsupported country code may return no bank details
- Spaces in IBAN are accepted and normalized
- Very new or obscure bank IBANs may not resolve bank name/BIC
- Network timeout if underlying openiban.com is unavailable
