OpenSecrets killed their public API in April 2025. We rebuilt it — bigger. Campaign finance aggregates, lobbying disclosures, corporate accountability records, private equity mapping, patent data, and AI-detected connections across 45+ public datasets. 27 endpoints across 5 data packs. Free tier, no credit card.

All data is aggregated from public sources: FEC filings, Senate lobbying disclosures, USPTO, SEC EDGAR, OSHA, EPA, and 40+ more. Individual donor identities are never exposed — federal law (52 U.S.C. § 30111(a)(4)) prohibits commercial use of individual contributor information, and our API enforces this at the data layer.
