## 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 hergert-synthora-iban-check-f190adf5 -d '<json body>'
```

Example prompt: Can you check whether the IBAN GB82WEST12345698765432 is valid and tell me what bank and country it belongs to?

## When to prefer this

Choose this endpoint when you need a structured, detailed IBAN validation with bank code extraction, country identification, and formatted output in a single lightweight call. It is ideal for pre-payment verification, fintech onboarding flows, or any agent workflow that needs to confirm IBAN correctness before initiating a financial transaction. At $0.005 per call it is cost-effective for per-transaction checks.

## Known failure modes

- Invalid or malformed IBAN string returns valid:false with error detail in checks object
- Unsupported country prefix may result in incomplete bank name resolution
- Network or service errors return ok:false with an error message field
- Missing iban field in request body returns an error response

## Output

A JSON object containing: a boolean 'valid' field indicating overall validity, the normalized 'iban' and 'formatted' IBAN (with spaces), the 'country' code and 'country_name', 'bank_code', 'bban' (basic bank account number), 'check_digits', 'length' and 'expected_length', and a 'checks' object with granular validation sub-results. Top-level 'ok' indicates API call success and 'niche' confirms the operation type.
