## 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-syntexa-ch-iban-al-validator-67c22a9e -d '<json body>'
```

Example prompt: Can you check whether AL47212110090000000235698741 is a valid Albanian IBAN — specifically that it's 28 characters long and passes the mod-97 checksum?

## When to prefer this

Use this endpoint when you specifically need to validate an Albanian (AL) IBAN and want strict country-specific length (28) and mod-97 verification. Prefer the free sandbox endpoint POST /v1/sandbox/check-iban-al first during development. For validating IBANs from other countries, use the corresponding country-specific endpoint (e.g. AT, AZ, BH). For a generic multi-country IBAN check, use the general IBAN validator sibling endpoint instead.

## Known failure modes

- IBAN string is empty or missing — returns invalid/error
- IBAN does not start with 'AL' country code — returns invalid
- IBAN length is not 28 characters — returns invalid
- IBAN fails mod-97 checksum — returns invalid
- Malformed input or non-string value — may return error
- Payment of $0.004 USDC not provided — returns 402 Payment Required

## How this service works

Call when an agent needs whether an IBAN is a mod-97-valid AL number of length 28. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/check-iban-al first.

## Output

A boolean or structured response indicating whether the provided string is a valid Albanian (AL) IBAN — confirming it is exactly 28 characters long and passes the ISO 7064 mod-97 checksum algorithm.
