## 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 saylor-innovations-iban-validator-9c433018
```

Example prompt: Can you check whether this IBAN is valid: GB29 NWBK 6016 1331 9268 19? I need to know if the checksum passes and what country it belongs to before I submit the payment.

## When to prefer this

Choose this endpoint when you need server-side IBAN validation with ISO 7064 MOD 97-10 checksum verification, especially when you also want structured metadata like the parsed country name, check digits, and normalization — rather than a simple client-side regex check. Useful before initiating SEPA transfers, onboarding international banking customers, or validating supplier payment details.

## Known failure modes

- Missing 'iban' query parameter returns an error
- Non-IBAN string returns valid=false with structure_ok=false
- IBAN with correct structure but bad checksum returns valid=false with checksum_ok=false
- Unsupported or unrecognized country code may return partial results
- Malformed request returns HTTP 4xx error

## How this service works

IBAN validation with ISO 7064 MOD 97-10 checksum - country code, check digits and pass/fail

## Output

A JSON object containing: a boolean 'valid' indicating overall pass/fail, 'checksum_ok' boolean for MOD 97-10 result, 'structure_ok' boolean for format compliance, 'check_digits' string, 'country' name, 'normalized' IBAN string, 'length' integer, and optional 'note' and 'source' fields providing context.
