## 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-lc-validator-60386217 -d '<json body>'
```

Example prompt: Can you check if LC59667700000002000001234567890 is a valid LC IBAN — I need to know if it passes the mod-97 checksum and is the right 32-character length?

## When to prefer this

Use this endpoint when you specifically need to validate an LC-country IBAN (Saint Lucia, 32 characters) with mod-97 checksum verification. Prefer the free sandbox endpoint POST /v1/sandbox/check-iban-lc for testing. Use this paid endpoint in production flows where authoritative validation is required. For other IBAN country codes (e.g. MU), use the corresponding country-specific sibling endpoint.

## Known failure modes

- Input string is not 32 characters — returns invalid result
- Input does not begin with LC country code — fails format check
- Mod-97 checksum fails — IBAN flagged as invalid
- Empty or missing value field — request rejected
- Non-string or malformed input — may return error or invalid

## How this service works

Call when an agent needs whether an IBAN is a mod-97-valid LC number of length 32. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/check-iban-lc first.

## Output

Returns a boolean or structured result indicating whether the submitted string is a valid LC-format IBAN: correctly 32 characters in length and passing the mod-97 checksum algorithm used for IBAN validation.
