## 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 romanian-iban-mod-97-validator-68fe6c9a -d '<json body>'
```

Example prompt: Can you check whether 'RO49AAAA1B31007593840000' is a valid Romanian IBAN — does it pass the mod-97 checksum and is it exactly 24 characters?

## When to prefer this

Use this endpoint when you need deterministic, rules-based mod-97 IBAN validation specifically for Romanian (RO) IBANs. It is a cheap, fast, pure-computation check with no network dependencies or LLM involvement — ideal for pre-validating bank account numbers before payment processing, user onboarding, or financial data quality checks. Try the free sandbox POST /v1/sandbox/check-iban-ro first if available.

## Known failure modes

- Invalid or missing 'value' field returns an error
- IBAN not starting with 'RO' prefix fails country check
- IBANs not exactly 24 characters in length are rejected
- Strings that fail the mod-97 checksum computation return invalid
- Malformed input or empty string returns a validation error
- Costs $0.01 USDC per call even if input is invalid

## How this service works

Call when an agent needs whether an IBAN is a mod-97-valid RO number of length 24. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/check-iban-ro first.

## Output

Returns a validation outcome indicating whether the submitted string is a mod-97-valid Romanian IBAN of exactly 24 characters, including pass/fail status and likely the reason for failure if invalid.
