Find companies

find_companies

Read-only

Find up to 50 legal entities by county, Estonian Classification of Economic Activities (EMTAK), revenue, employees or observed Register of Economic Activities (MTR) activity. Can exclude companies with current tax debt (no_tax_debt). Licence presence is not proof of compliance. Sort by metric and direction; default revenue descending, missing values last. At most 40 candidate pages or 80 tax-debt checks, subject to distinct-code allowance; no continuation cursor. Check result completeness. Missing source data can yield an empty list. English activity labels include attribution and disclose broader-label fallbacks. Use search_companies for a name, or get_company for a listed code. Do not look up natural persons or personal contact details.
