## 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 iban-validate-445077f6
```

Example prompt: Can you check if the IBAN DE89370400440532013000 is valid and tell me what country it belongs to?

## When to prefer this

Use this endpoint when you need a lightweight, no-signup IBAN validation that also extracts the country code, paid per-call in USDC. Prefer this over building your own checksum logic or using account-based services when operating in a crypto-native, keyless payment flow via x402.

## Known failure modes

- Invalid or malformed IBAN returns valid:false with no country
- Missing IBAN parameter may return a 400 or empty response
- Non-IBAN strings (e.g. credit card numbers) may return valid:false
- Payment failure (402) if USDC balance insufficient for the $0.001 call fee

## How this service works

Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.

## Output

Returns a JSON object containing the original IBAN string, a boolean `valid` field indicating whether the IBAN passes format and checksum validation, and a two-letter ISO country code extracted from the IBAN prefix.
