private_searchFind US businesses by name when you do not yet know which one you want. Full-text ranked search over 30.6M entities from 56 state and territory registries. Use it to browse candidates or check whether a name exists at all; use private_resolve instead when you need to identify oneprivate_entityYou have already identified a company and now need the full official record: current status, incorporation date, EIN, registered agent, every officer with their role, addresses, and filing history. This is the record a state government actually holds, so use it to settle questionprivate_officer_searchFind which companies a named person is an officer, director or registered agent of. Use it to check whether a counterparty is who they claim, to map the other entities behind one operator, or to find every company a person controls before signing with any of them. Covers 21.2M ofprivate_browseBuild a list of companies matching criteria rather than looking one up: state, industry (NAICS), entity type, age, city, ZIP. Use it for prospecting, market sizing, or finding every business of a kind in a place. Ask for an industry with the naics filter — 23 is construction, 238private_ceo_searchFind the chief executive, president, chairman or manager behind a company, or find every company a named executive runs. Use when the question is "who is actually in charge here" rather than "does this company exist".

This is a succession and acquisition signal: it usually means an owner-operated company with no management layer. Use it to build acquisition target lists or to judge wprivate_statsCheck what this dataset actually covers before relying on it.

Use this when you have a company name from a document, email or user message and need to identify the actual registered private_what_changedWhat has actually CHANGED about one company, with the date we observed each change and cryptographic proof. State registries publish only current values and keep no history, so this answers questions no registry lookup can: did this company change its registered agent, did its stprivate_recent_changesCompanies that changed recently, across a state or a field — for finding corporate events rather than looking one company up. A registered-agent change signals a sale, restructuring or change of counsel; a status change is the difference between a live prospect and a dissolved onRecent checks
