## 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 agentshelf-iban-bosnia-herzegovina-validator-87c6e0d9 -d '<json body>'
```

Example prompt: Can you check if BA391290079401028494 is a valid Bosnian IBAN — I need to confirm the mod-97 checksum and that it's exactly 20 characters before I process this payment?

## When to prefer this

Use this endpoint when you specifically need to validate a Bosnia and Herzegovina (BA) IBAN and require both the mod-97 checksum validation and the exact 20-character length check. Prefer the free sandbox endpoint POST /v1/sandbox/check-iban-ba first during development or testing to avoid the $0.006 USDC charge. Choose this over generic IBAN validators when you need a lightweight, single-country BA-specific check with confirmed payment-grade reliability.

## Known failure modes

- IBAN fails mod-97 checksum — returns invalid result
- IBAN is not exactly 20 characters — fails length validation
- IBAN does not start with 'BA' country code — fails country prefix check
- Input value is empty or exceeds maxLength — request rejected
- Non-string or malformed input body — schema validation error
- Network timeout or service unavailability — 5xx error

## How this service works

Call when an agent needs whether an IBAN is a mod-97-valid BA number of length 20. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/check-iban-ba first.

## Output

Returns a boolean or structured result indicating whether the provided string is a mod-97-valid Bosnian IBAN of the correct 20-character length, along with any relevant validation details such as checksum pass/fail and length conformance.
