GovInfo API & Bulk Data (U.S. GPO)

GovInfo API & Bulk Data (U.S. GPO) is a rest api from U.S. Government Publishing Office (GPO) providing politics & elections data. Official U.S. Government Publishing Office API and bulk-data repository for federal legislative and regulatory documents. A Polymarket bot can use it to track bill status/text and Federal Register actions to objectively resolve policy-outcome markets (will a bill pass, will a rule take effect) directly from the authoritative government source.
