Pay-per-result data feeds for AI agents, trading systems, and sales teams. Every Actor reads official or public primary sources — state open-data portals, SAM.gov, USAspending, ClinicalTrials.gov, public ATS job boards, the Polymarket trade tape — and returns flat, schema-stable JSON priced per record. No subscriptions; Apify's free plan covers trying everything here.
