eCFR US Federal Agencies Scraper

Extract the complete directory of US federal agencies with their CFR (Code of Federal Regulations) title and chapter cross-references — sourced from the official eCFR (Electronic Code of Federal Regulations) administered by the Office of the Federal Register and the Government Publishing Office.

This Actor wraps the eCFR public agencies API into a flat, denormalized dataset showing exactly which CFR titles and chapters each federal agency administers. Critical for govtech, regulatory compliance, federal contracting research, and lobbying intelligence workflows.

• CFR cross-references — Every record includes the list of CFR titles + chapters that agency administers.
• Parent / sub-agency relationships — Sub-agency records include parent agency name and slug.
• Sortable, filterable — Filter by agency name, CFR title number, or sub-agency inclusion.
