## 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-validator-0d3194bc
```

Example prompt: Can you check whether the IBAN GB29NWBK60161331926819 is valid and tell me what country and bank code it corresponds to?

## When to prefer this

Use this endpoint when you need a quick, cheap, single-call IBAN validation that also returns parsed components (country, bank code, check digits) without setting up a local library or handling the complex IBAN checksum algorithm yourself. Ideal for payment flows, form validation, or data enrichment pipelines where IBAN accuracy is critical.

## Known failure modes

- IBAN with invalid check digits returns valid=false with an error message
- Malformed or empty IBAN string returns valid=false with an error description
- Unsupported or unknown country prefix may result in null bank_code or country
- Network or service errors may return non-200 HTTP responses

## How this service works

Use when you need to check whether an IBAN is valid and extract its country, bank code and check digits.

## Output

A JSON object with a boolean 'valid' field, a nullable 'country' string (ISO country code), a nullable 'bank_code' string, a nullable 'check_digits' string, and a nullable 'error' string explaining any validation failure.
