Check an Estonian company by API: e-Business Register

e-Business Register (RIK) · read from the national register · checked 11 November 2026

The official route

Estonia's e-Business Register is run by RIK (Registrite ja Infosüsteemide Keskus). Two routes need no contract (read 2026-11-06).

The autocomplete service, https://ariregister.rik.ee/eng/api/autocomplete?q=. RIK's page describes it as open to the public, without user name, password or contract. It returns at most 10 results, each with name, status and address.
The open-data bulk files on the download page: basic data, general data and the key indicators of annual reports. They are plain HTTPS downloads.

The open-data site's licence link points to CC BY 4.0. The download page says downloading requires acceptance of the licence terms. That acceptance is a page dialog we could not read as text. Since 1 November 2024 the files hold no personal identification numbers.

Where it gets hard

The per-company REST and X-Road services (company detail, annual reports) need a contract with RIK.
Without one you combine two things: live name, status and address from autocomplete, and everything else from bulk files you download and index yourself. The files we use come to about 340 MB a week.
Annual-report figures depend on how the report was filed. Bolt Technology OÜ filed its 2025 report as PDF only, and the open data then holds just revenue, assets and employees.
RIK's terms say other public data that is not open data may not be reused, so stay with the open-data files and autocomplete.

One call

{"query": "Bolt Technology OÜ", "country": "EE"}

The call is POST https://api.boscolabs.dev/v1/counterparty-check. The registry code (12417834) is the safer query when you have it.

What we do not cover

Officers, shareholders and beneficial owners. RIK publishes files for them, and we never download those.
Sole traders (FIE): a lookup by their code fails without a charge.
Legal form, VAT number and figures come from our weekly index of the bulk files, so they can be up to a week old.
