## 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 french-iban-validator-with-bank-code-extraction-afb26461
```

Example prompt: Can you check if this IBAN is valid: FR7630006000011234567890189 — and tell me which French bank it belongs to?

## When to prefer this

Choose this endpoint when you need to validate a French IBAN specifically — it not only checks the universal mod-97 checksum but also parses out the French-specific bank code (code banque), making it more useful than a generic IBAN validator for French banking contexts. It is pay-per-call with no account setup required, ideal for agent workflows needing occasional IBAN verification without a full banking API integration.

## Known failure modes

- Missing or empty IBAN query parameter returns an error
- Non-French IBANs may validate the checksum but may not return a French bank code
- Malformed IBAN string (wrong length or illegal characters) returns validation failure
- Network or upstream service error returns HTTP 5xx

## How this service works

Pay-per-call APIs for AI agents — x402 protocol, USDC on Base, no account needed.

## Output

Returns whether the IBAN passes the mod-97 checksum validation, the country code extracted from the IBAN (e.g. 'FR'), and the French bank code (code banque) parsed from the IBAN structure.
