## 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-md-validator-mod-97-5fe6e8f6 -d '<json body>'
```

Example prompt: Can you check whether MD49125007294100013104168 is a valid Moldovan IBAN — does it pass the mod-97 checksum and is it the right length?

## When to prefer this

Use this endpoint when you specifically need to validate a Moldovan (MD) IBAN and require both mod-97 checksum verification and length conformance (24 characters). Prefer the free sandbox endpoint POST /v1/sandbox/check-iban-md for testing before using this paid production endpoint. Choose sibling endpoints for other country-specific IBANs (e.g. GI, HR, HU). Do not use a generic IBAN validator if country-specific MD validation is required.

## Known failure modes

- Input string is empty or missing — returns invalid/error
- IBAN is correct length but fails mod-97 checksum — returns invalid
- String has MD prefix but wrong length (not 24 chars) — returns invalid
- Non-MD country code supplied — returns invalid or country mismatch error
- Malformed input with special characters — may return parse 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 MD number of length 24. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/check-iban-md first.

## Output

Returns a boolean or structured result indicating whether the supplied string is a valid Moldovan (MD) IBAN — confirming it is exactly 24 characters long, has the correct MD country code prefix, and passes the ISO 7064 mod-97 checksum algorithm. No network calls are made to external banking systems.
