Find people at a company and optionally discover and verify their business email. Identify the company by bare domain, by company name, by LinkedIn company URL, or pass a list of domains to run a batch where every output row echoes its source domain. Results are filtered by job title include and exclude lists, by normalized seniority, by normalized department and by country. A four layer cascade runs the company website, public search and a licensed database fallback, with company match scoring on every candidate; nothing here scrapes LinkedIn directly. Email discovery runs a two provider waterfall and verification escalates catch all domains to a second provider for a definitive answer. Provider keys are yours: you supply them, the vendors bill you directly, and the actor does not mark them up. Without a Serper key the search layer is off and coverage drops sharply. targetCount is a hard cost cap because billing is per person actually returned. Requires an APIFY_TOKEN and consumes Apify credits. Read only: it finds and verifies, it writes nothing.
