# Members and shareholders of an Estonian company

Since 2023 the Estonian register itself keeps the share register of OÜ companies: 390,000 member lines published daily, with percentage, nominal value, ownership type and date. Sirenic serves those lines for a company, names legal persons with their registrikood or foreign code, and counts natural persons without naming them — the same rule as for Latvia. AS shareholders and founders recorded beside the card, share pledges and conditional transfers, and capital come with it.

## What the route returns

Catalogue description, exactly as agents read it:

**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.**

## Expected identifier

8-digit Estonian registration code (registrikood).

> ⚠️ A wrongly formatted identifier in the **path** returns `400` and is **not billed** — but it costs you a round trip. It is the leading cause of failed calls on the foreign routes. A **search** parameter, by contrast, is cleaned up: unsupported characters are stripped and the usable query is served.

## Price and billing

Price: **$0.02**. The authoritative amount is the one in the `402` quote returned by the route itself — not this text, which derives from the same grid but is still just a page.

An error response **cancels the payment**: a `400`, `404` or `503` is never billed. An upstream outage closes the route with a `503` rather than serving a degraded response.

## Calling the route

```
# 1. Le devis, sans rien payer : la route répond 402 avec son montant
curl -i https://api.sirenic.eu/v1/eu/entreprise/EE/{registrikood}/associes

# 2. L'appel réglé — le client x402 paie le devis et rejoue la requête
npx x402-fetch https://api.sirenic.eu/v1/eu/entreprise/EE/{registrikood}/associes

# 3. Ou en MCP, dans Claude Code / Cursor / un agent
claude mcp add --transport http sirenic https://api.sirenic.eu/mcp
```

## What this route does not do

Dematerialised AS shares are held by the central depository, outside the register: an AS with no line does not have “zero shareholders”. Legal persons only.

## Neighbouring routes

- `/v1/eu/entreprise/EE/{id}` — $0.01
- `/v1/eu/entreprise/EE/{registrikood}/dirigeants` — $0.01
- `/v1/entreprise/{siren}/capital` — $0.35

## How you pay

Every route is paid **per call**, in USDC or EURC on the Base network, over the x402 protocol: no account to create, no API key, no subscription. The first call returns a `402` quote your client settles, then replays the call. A failed call is never billed.

Would you rather have a euro invoice and prepaid credits? That is **in preparation**, and we will not announce a date until it is open. Write to [contact@sirenic.eu](mailto:contact@sirenic.eu?subject=Euro%20credit%20packs) and we will let you know when it opens.

Paid responses are **Ed25519-signed**: you can later prove what was served to you, and when. The whole catalogue is free to read in the [OpenAPI document](https://api.sirenic.eu/openapi.json) and in [llms.txt](https://api.sirenic.eu/llms.txt).

**One call, end to end**
