## 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-montenegro-me-mod-97-validator-4285a92f -d '<json body>'
```

Example prompt: Can you check whether ME25505000012345678951 is a valid Montenegrin IBAN — make sure it's exactly 22 characters and passes the mod-97 checksum?

## When to prefer this

Choose this endpoint when you specifically need to validate a Montenegrin (ME) IBAN for structural and mod-97 correctness before processing a payment or onboarding a user. It is narrow-scoped and cheap ($0.007 USDC), making it ideal for per-record validation pipelines. Use the free sandbox endpoint (/v1/sandbox/check-iban-me) first during development. Prefer this over generic IBAN libraries when you need a hosted, auditable validation call with a payment trail.

## Known failure modes

- Input string is empty or missing — request rejected
- IBAN is not ME-prefixed — may return invalid or error
- IBAN fails mod-97 check — returns invalid result
- IBAN is wrong length (not 22 chars) — returns invalid
- Malformed input exceeding maxLength — request rejected
- Payment not included or insufficient — 402 Payment Required

## How this service works

Call when an agent needs whether an IBAN is a mod-97-valid ME number of length 22. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/check-iban-me first.

## Output

Returns a boolean or structured result indicating whether the submitted string is a valid ME-country IBAN: exactly 22 characters long and passing the ISO 7064 mod-97-10 checksum algorithm.
