Federal Register API

Data

2 tokens / call

The US government's daily journal, queryable. Search every Federal Register document — final rules, proposed rules, notices and presidential documents — by keyword, type, agency and date ('artificial intelligence' final rules: 318 and counting), with title, abstract, agencies, publication date and both HTML and PDF links, plus full document detail with CFR references, docket ids, effective dates, comment deadlines and raw-text URLs. A dedicated executive-orders endpoint covers every EO since the Clinton administration with number, signing date and president — filter by president (Obama: exactly 294) or signing-date range; friendly names like 'obama' and 'biden' resolve to the official identifiers. An agencies directory (with the slugs the filters expect) rounds it out. Responses proxy the official National Archives API with 1-hour edge caching, and the pagination quirk where the upstream floors page size at 20 is handled so pages never skip documents. Legal tech, compliance monitoring, policy research, lobbying intelligence and newsrooms — regulatory change, at API speed.
