## 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-lb-lebanon-validator-358c8297 -d '<json body>'
```

Example prompt: Can you check whether 'LB62099900000001001901229114' is a valid Lebanese IBAN — specifically that it's exactly 28 characters and passes the mod-97 checksum?

## When to prefer this

Use this endpoint when you specifically need to validate a Lebanese (LB) IBAN for mod-97 compliance and 28-character length. Choose this over generic IBAN validators when you need a lightweight, deterministic, network-free check with no LLM involvement. Try the free sandbox endpoint POST /v1/sandbox/check-iban-lb first during development to avoid charges.

## Known failure modes

- IBAN does not start with 'LB' — returns invalid
- IBAN is not exactly 28 characters — returns invalid
- IBAN fails mod-97 checksum — returns invalid
- Empty or missing value field — returns error
- Payment of $0.003 USDC not received — returns 402 Payment Required
- Malformed request body — returns 400 Bad Request

## How this service works

Call when an agent needs whether an IBAN is a mod-97-valid LB number of length 28. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/check-iban-lb first.

## Output

A boolean or structured result indicating whether the supplied IBAN is a valid Lebanese (LB) IBAN — confirming it is exactly 28 characters long and passes the ISO 7064 mod-97 checksum algorithm.
