## 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 latvian-iban-validator-lv-length-21-892bac7a -d '<json body>'
```

Example prompt: Can you check whether LV80BANK0000435195001 is a valid Latvian IBAN — does it pass the mod-97 checksum and is it exactly 21 characters?

## When to prefer this

Use this endpoint when you specifically need to validate a Latvian (LV) IBAN and want a dedicated, country-specific mod-97 check with known length enforcement (21 characters). Prefer the free sandbox endpoint /v1/sandbox/check-iban-lv for testing. Choose this over a generic IBAN validator if you want a lightweight, single-country focused microservice with a fixed low cost per call.

## Known failure modes

- Input string is empty or missing — returns validation error
- IBAN does not start with LV country code — returns invalid
- IBAN length is not exactly 21 characters — returns invalid
- Mod-97 checksum fails — returns invalid
- Malformed request body — returns 400 or schema error
- Payment of $0.006 USDC not provided — returns 402 Payment Required

## How this service works

Call when an agent needs whether an IBAN is a mod-97-valid LV number of length 21. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/check-iban-lv first.

## Output

A boolean or structured result indicating whether the supplied string is a valid Latvian IBAN — specifically that it starts with 'LV', is exactly 21 characters long, and passes the ISO 7064 mod-97-10 checksum calculation.
