search_companiesFull-text search across 128 million registered companies in official US and Canadian state registers — by legal name, officer or director name, phone number, email or website. Contact-shaped queries (phone/email/website) resolve through the official records carrying that exact value; the response's matched_by field says which channel matched. Filters mirror the website's facet rail; the response carries up to 25 matching profiles plus facet counts. Facet counts describe every name match (not just the filtered set), so they show which filter values would widen or narrow the search. Records are for human review — not for automated decisions covered by the FCRA.
list_jurisdictionsThe taxonomy for building queries: countries with regions (and cities when a country+region is given), industries, statuses, and total company count. Call this first to find valid slugs for the other tools.
