Full-text search of the US Code of Federal Regulations (eCFR). Find current rules by keyword or agency with citations, headings, and direct links.
What it does
- Searches the full text of the current CFR through the official eCFR search API (no API key needed).
- Optionally restricts the search to one or more agencies.
- Keeps only the current version of each provision and dedupes repeated citations.
- Exports clean, flat records with the CFR citation, headings, a highlighted excerpt as plain text, and a direct ecfr.gov link, plus an aggregate summary in OUTPUT.
Input
| Field | Type | Description |
|---|---|---|
query | string | Required. Full-text search query, for example "incident reporting requirements". |
agencySlugs | array | Optional agency slugs to restrict the search, for example ["environmental-protection-agency"]. Valid slugs: https://www.ecfr.gov/api/admin/v1/agencies.json |
maxItems | integer | How many results to return (auto-paginated, max 500). Default 50. |
Example:
{"query": "incident reporting requirements","agencySlugs": ["federal-communications-commission"],"maxItems": 50}
Output
Each dataset item is one CFR provision:
{"type": "Section","cfrTitle": "30","part": "285","section": "285.830","heading": "What are my incident reporting requirements?","partHeading": "Renewable Energy and Alternate Uses of Existing Facilities on the Outer Continental Shelf","excerpt": "must report all incidents listed in § 285.831 to BSEE, according to the reporting requirements...","startsOn": "2024-07-15","url": "https://www.ecfr.gov/current/title-30/section-285.830","score": 38.608624}
The run's key-value store record OUTPUT holds a summary: total matches, items returned, and a breakdown by CFR title.
Pricing
Pay per result, plus standard Apify platform usage.
Data source
The official eCFR search API at ecfr.gov, maintained by the US Government Publishing Office and the Office of the Federal Register. The API is public and keyless. Search results reflect the current published eCFR text, which is an unofficial but continuously updated edition of the CFR. This Actor caps results at 500 per run and retries rate limit or server errors with backoff.
