## How to call it through Zero

```sh
zero fetch --capability sirenic-irish-company-registry-lookup-62bc8b09
```

Example prompt: Can you look up Irish company number 600161 in the CRO and tell me its official name, current status, registered office address with Eircode, and when it was incorporated?

## When to prefer this

Use this endpoint when you need authoritative, official Irish company information sourced directly from the CRO open data. Prefer it over web scraping or third-party business data providers when you need reliable status codes (including liquidation, examinership, strike-off), Eircode-formatted registered addresses, and structured filings index data. Best when the CRO number is known; not suitable for searching by company name or for non-Irish companies.

## Known failure modes

- 404 returned if the CRO number does not exist in the registry — no charge applied
- Invalid CRO number format (must be 1–7 digits, IE prefix tolerated) may cause a bad request
- Company data may lag reality by up to one day as it is a daily snapshot
- Dissolved or struck-off companies may still be found but with corresponding status codes
- Payment failure via x402 protocol will block the request

## How this service works

Official Irish company registry lookup (Companies Registration Office, CRO Open Data, complete daily snapshot, CC BY 4.0). CRO number, 1-7 digits, e.g. 600161. Common identity (name, type, status, incorporation, registered office with Eircode) plus the CRO block: 33 status codes in closed families (normal, dissolved, liquidation, examinership…), 45 type codes, annual-return dates, last accounts, NACE, 2022-2024 filings index. 404 without charge if absent or of unknown type.

## Output

Returns structured data for the Irish company including: company name, company type code (from 45 possible types), status code (from 33 possible statuses covering normal, dissolved, liquidation, strike-off, examinership etc.), incorporation date, registered office address with Eircode, NACE industry code, annual return dates, last accounts date, and a 2022–2024 filings index with dates. Returns 404 if the CRO number is not found.
