## How to call it through Zero

```sh
zero fetch --capability sirenic-estonian-company-members-shareholders-ecebd4d9
```

Example prompt: Can you pull the shareholder and ownership structure for the Estonian company with registrikood 14532901, including holding percentages, any share pledges, and the capital details?

## When to prefer this

Choose this endpoint when you need official, registry-sourced ownership and shareholding data for an Estonian legal entity, especially for KYB, AML, or corporate group mapping workflows. It is GDPR-compliant (natural persons counted, not named) and sourced from the authoritative RIK e-Business Register with daily refresh. Prefer it over scraped or third-party aggregators for compliance-grade due diligence on Estonian companies.

## Known failure modes

- 404 with payment cancelled if the registrikood is unknown or does not exist in the register
- 404 with payment cancelled if the registrikood belongs to a sole proprietorship (FIE) — only legal persons are supported
- Incomplete data if shareholders were recorded off-card or the daily snapshot has not yet updated
- Foreign corporate shareholders may have limited detail (foreign code and country only, no domestic registry link)

## How this service works

Estonian company members and shareholders from the official e-Business Register share register (RIK, CC BY 4.0, daily photo): holding percentage, nominal value and currency as published, ownership type, registration date; AS shareholders and founders recorded off-card; share pledges; capital. Corporate holders are named with their registrikood or foreign code and country; natural persons are COUNTED, never named (GDPR). Group links for KYB. Legal persons only. 8-digit registrikood.

## Output

A structured response containing the list of shareholders (corporate entities named with their registry code and country; natural persons counted but not named per GDPR), each with holding percentage, nominal value and currency, ownership type, and registration date. Also includes share pledge information and capital figures for the company, and founder records for AS entities.
