sirenic

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.

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.

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 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 and in llms.txt.
