## 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 irish-cro-company-number-verification-9a637b72 -d '<json body>'
```

Example prompt: Before we pay this invoice, can you verify that CRO number 123456 is a legitimately registered Irish company and tell me the registered name on file?

## When to prefer this

Choose this endpoint when you need a focused, low-cost real-time check of a single Irish CRO company number before processing a supplier invoice or onboarding a new vendor. It is the cheapest and most targeted check in the suite — ideal when you only need CRO validation and not a full multi-check verification bundle. Prefer this over manual CRO lookups or full-suite verification when speed and cost matter and CRO status is the only unknown.

## Known failure modes

- Invalid or malformed CRO number format returns a FAILED outcome with a relevant reason code
- CRO number does not match any registered company returns FAILED
- CRO registry is temporarily unavailable causing a service error
- Payment not included or insufficient USDC payment via x402 returns 402 Payment Required
- CRO number exceeds 16-character maximum returns validation error

## How this service works

An independent third-party agent that tells your agent whether to pay an Irish supplier invoice: EXECUTE, REJECT or FLAG. CRO, VIES, IBAN, 3-way match and signature checks. From $0.005 per call in USDC on Base (x402). No account.

## Output

Returns a JSON object with the check type ('CRO'), outcome ('PASSED' or 'FAILED'), ISO 8601 timestamp of when the check was performed, a machine-readable reason code (e.g. 'CRO_NORMAL'), and the official registered company name as held by the CRO.
