## 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-mu-mod-97-validator-8786b401 -d '<json body>'
```

Example prompt: Can you check whether MU43BOMM0101123456789101000MUR is a valid Mauritius IBAN — specifically that it's 30 characters long and passes the mod-97 checksum?

## When to prefer this

Use this endpoint when you specifically need to validate a Mauritius (MU) IBAN for mod-97 correctness and exact 30-character length compliance. Prefer the unpaid sandbox POST /v1/sandbox/check-iban-mu for testing or development. Choose this paid endpoint when operating in production and requiring a definitive, authoritative check against the MU IBAN standard.

## Known failure modes

- Input string missing or empty — validation cannot proceed
- IBAN fails mod-97 check — returns invalid result
- IBAN is not 30 characters — length mismatch for MU format
- Input exceeds maximum allowed length (20000 chars)
- Payment of $0.01 USDC not fulfilled — 402 response requiring payment
- Malformed JSON body — request rejected

## How this service works

Call when an agent needs whether an IBAN is a mod-97-valid MU number of length 30. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/check-iban-mu first.

## Output

A boolean or structured response indicating whether the supplied string is a valid Mauritius (MU) IBAN — confirming it is exactly 30 characters long and satisfies the mod-97 checksum algorithm used for IBAN validation.
