Short answer. The official source is the e-Business Register (RIK). Start there, then check what a register does not show.
Where. e-Business Register (RIK): https://ariregister.rik.ee/
What you can see for free. Per RIK, data of legal entities other than your own can be accessed free of charge in the e-Business Register Portal search without logging in (except documents from the file of non-profit associations). Search by name or registry code, or use the detailed search by legal form, address or field of activity.
Steps.
What the register does not show. A registry record does not verify business activity, creditworthiness or sanctions status, and it is not a news check.
What a Dutiful report adds. For Estonia: registry profile, legal form, status, capital, registration date and address, with officers on a best-effort basis. Owners and financial figures are not covered. Plus a sanctions screen (OFAC SDN and UK Sanctions List) and a public news and web scan, with sources. Sample: /sample.
