How this service works

Searches Federal Register documents via the official API (public domain). Filter by terms, agency slug, document type (rule, proposed rule, notice, presidential document) and date range. Each result includes title, document number, type, agencies, publication date, effective date, comment end date, abstract, and PDF/HTML URLs. `limit` max 50.

Output

Returns a JSON object with a count of returned results, total matching documents, a source attribution to the Federal Register API, and an array of document objects each containing: title, document type (Rule/Proposed Rule/Notice/Presidential Document), abstract snippet, PDF URL, HTML URL, publishing agencies, effective date, publication date, comments close date, and document number.

Example use cases

Track new financial regulations

“Find the latest Federal Register rules and proposed rules from the SEC and Treasury published after 2026-01-01 — I want to see up to 20 results so I can track new financial regulatory requirements.”

Monitor agency rulemaking for compliance

“Search the Federal Register for any OSHA rules or proposed rules about workplace safety published between 2025-01-01 and 2025-12-31, up to 50 results.”

Research air cargo security regulations

“Pull all Federal Register notices and rules related to air cargo screening from US Customs and Border Protection — give me up to 15 results so I can review the regulatory history.”

Technical details

Endpoint

GEThttps://api.sitecheck-api.workers.dev/api/law/federal-register?utm_source=zero.xyz

When to prefer

Use this endpoint when you need structured, searchable access to US Federal Register documents including final rules, proposed rules, notices, and presidential documents — especially when filtering by agency, date range, or document type. Prefer this over web scraping federalregister.gov directly, as it returns clean structured JSON with PDFs and metadata. Best suited for compliance monitoring, regulatory research, and legal due diligence workflows.

Side effects

Invalid document type enum returns no results or error
Agency slug not recognized returns empty results
Date range with no matching documents returns empty results array
Query string exceeding 200 characters may be rejected
Limit outside 1-50 range may default or return an error
Upstream Federal Register API downtime causes service unavailability
