How this service works
US federal regulation search — find Federal Register rules, proposed rules, notices and presidential documents by full text, agency, type, date, docket, RIN, significance or CFR part, with abstract, effective date, comment deadline and official links for each. Use to check whether a rule exists on a subject, what an agency has issued, or when a comment period closes.
Output
Returns a paginated list of Federal Register documents matching the query, each including document title, abstract, agency, document type (rule/proposed rule/notice/presidential), effective date, comment deadline, CFR citations, docket ID, RIN, publication date, and a link to the official Federal Register entry. Also includes total result count, page info, and applied filter metadata.
Example use cases
Comment deadline lookup for compliance team
“Find any proposed rules from the EPA about clean water standards with an open comment period — I need the document title, abstract, comment deadline, and a link to each one.”
RIN tracking for a lobbying firm
“Look up the Federal Register entry for RIN 1545-BQ44 and give me the full abstract, effective date, agency, and document type.”
CFR part monitoring for legal counsel
“Search for all final rules that affect CFR Title 17, Part 240 published since 2024-01-01, ordered by newest — I need to know what the SEC has finalized this year in that part.”

Endpoint
GEThttps://us-regulations.use.x402atlas.com/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to find, verify, or enumerate specific US federal regulatory documents from the Federal Register by topic, agency, CFR citation, RIN, docket, or date. Prefer this over general web search when you need structured metadata (effective dates, comment deadlines, RINs, CFR parts) or need to programmatically filter by agency or document type. Use sibling endpoint US Regulation Updates for a recency-focused feed, or US Regulation Counts for aggregated statistics rather than individual documents.
Side effects
- No documents found for a narrow query — returns empty documents array with count 0
- Invalid agency slug returns an error or empty results — use /agencies endpoint to validate slugs first
- cfr_part provided without cfr_title returns a validation error
- Query string exceeds 200 characters returns a schema validation error
- Date format not YYYY-MM-DD returns a parsing error
- Page number beyond total_pages returns empty results
