Federal Register Monitor
Monitor the Federal Register — the daily journal of the US government — via the official federalregister.gov API. No key, no browser, pure official data.
New rules, proposed rules, notices and presidential documents publish every business day. This actor turns them into a structured feed — and, critically, tracks public comment deadlines so your team never misses its window to respond.
Modes
| Mode | What it returns |
|---|---|
feed | Newest documents — filterable by agency, doc type, date range, significance |
deadlines | Proposed rules whose comment window closes within N days (closingWithinDays) |
agency | Everything published by one agency (e.g. environmental-protection-agency) |
search | Keyword monitor across titles/abstracts (e.g. artificial intelligence, airworthiness) |
dockets | Documents linked to Regulations.gov comment dockets — with live comment counts |
Example inputs
Comment deadlines closing in the next 14 days:
{"mode": "deadlines", "closingWithinDays": 14}
Daily digest of new EPA actions (run on a schedule):
{"mode": "agency", "agency": "environmental-protection-agency", "publishedAfter": "2026-09-28"}
Everything mentioning a topic this month:
{"mode": "search", "query": "artificial intelligence", "publishedAfter": "2026-09-01"}
Full daily feed, only economically significant rules:
{"mode": "feed", "significantOnly": true, "publishedAfter": "2026-09-28"}
Why deadlines matter
When an agency publishes a proposed rule, it opens a public comment window (usually 30–90 days). Comments are the only formal channel to influence the final rule — and the deadline is hard. deadlines mode + daysUntilCommentClose gives compliance teams a watchlist they can act on.
Output fields
documentNumber, title, docType (Rule / Proposed Rule / Notice / Presidential Document), agencies, publicationDate, effectiveOn, commentsCloseOn, daysUntilCommentClose, significant (EO-12866 reviewed), abstract, docketIds, regulationsGovDocumentId + regulationsGovUrl + regulationsGovCommentsCount, cfrReferences, htmlUrl, pdfUrl.

Monitoring pattern
Schedule the actor daily (weekdays) with publishedAfter = yesterday, or run deadlines weekly for a rolling comment-window watch. Ideal for regulatory affairs, trade associations, law firms, GovCon teams, journalists.
Notes & limitations
- Data is the official Federal Register API — complete since 1994.
deadlinesscans recent proposed rules and filters client-side; very old rules with long windows are included when their close date is in range.- Some proposed rules have no comment deadline (e.g. corrections) — they're excluded from
deadlines. significantreflects the API's EO-12866 flag and is only populated on some documents.
Pricing
