# nimistu — Estonia's public-interest company register

> Free, ad-free open-data view of the Estonian Business Registry. 32 M+ records across 141+ tables (375,307 companies, 395,291 persons), 72+ government and open-data sources, daily-refreshed. Operated by Nimistu MTÜ (non-profit). Data is licensed CC-BY-SA 4.0.

## Core data

- [Company directory](https://nimistu.ee/): search and browse 375k+ active and historical Estonian companies by name, registration code, or address. Per-company canonical URL is `https://nimistu.ee/{regCode}-{slug}`.
- [Persons directory](https://nimistu.ee/isik/): board members, owners, beneficial owners, founders (395k+ entries). Sourced from the public Estonian Business Registry; identifier types are isikukood-hash (Estonian residents) and synthetic ext: identifiers (foreign founders without an Estonian personal code).
- [Data views](https://nimistu.ee/vaated): 38+ curated open-data views — politically exposed persons, foreign founders, procurement winners, top employers, tax debtors, by sector and county.
- [Sources](https://nimistu.ee/allikad): full catalog of upstream data sources (Äriregister, MTA, RIK, EMTA, NASDAQ Baltic, OpenSanctions, GLEIF, Wikidata, …) with refresh status.

## Developer / agent access

- [Lookup API](https://nimistu.ee/api/lookup): JSON lookup by registration code; pairs with the browser extension.
- [Browser extension](https://nimistu.ee/en/extensions): nimistu inserts a clean company / person card above Google, Bing and DuckDuckGo results — free, ad-free, no tracking. [Chrome](https://chromewebstore.google.com/detail/nimistu/jlbjncingochchkobhbpffdallkgceba) · [Firefox](https://addons.mozilla.org/firefox/addon/nimistu/).
- Markdown for agents: append `.md` to any page URL (e.g. `https://nimistu.ee/{regCode}-{slug}.md`, `https://nimistu.ee/isik/{id}-{slug}.md`) to get its main content as edge-cached markdown — preferred over HTML scraping. Equivalently, pass `Accept: text/markdown` to any page URL.
