## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

### What does Federal Register Monitor do?

**Federal Register Monitor** lists **US rules, proposed rules, notices and presidential documents** from the **official Federal Register API**, filtered by **topic, agency or CFR part**. It also has a **monitor mode** that returns **only documents it has not returned before**, so a daily schedule gives you just what is new. No key, no scraping.

Each row has:

- **document number, title and type** (rule, proposed rule, notice, presidential document)
- **agencies**
- **publication date, effective date and comment deadline** (and a flag that says whether the comment period is still open)
- **CFR references** (title and part, for example `40 CFR 60`)
- the **significant** flag (significant under Executive Order 12866, as marked by the Unified Agenda)
- the **abstract**
- **HTML and PDF links**
- **docket IDs** and the **Regulations.gov link** when the document has one

### Who is it for?

- **Compliance and regulatory affairs teams**: every new rule or proposal that touches the CFR parts you are subject to.
- **Law firms and consultants**: alerts for clients by agency, topic or CFR title, with comment deadlines.
- **Trade associations and advocacy groups**: proposed rules that are still open for comment.
- **Journalists and analysts**: significant rules by agency, as a feed or a spreadsheet.

### How to use it

1. Click **Start** with the default input: the 50 newest documents of the last 7 days.
2. Add filters: search terms, agencies (`EPA`, `Energy Department`), document types, CFR title or part, significant only, open for comments only.
3. For alerts, choose **Mode: Monitor** and **schedule** the Actor daily. The first run saves a baseline; every later run returns only new documents. Connect the dataset to Slack, e-mail or a webhook.

### Input example

```json
{
    "searchTerms": ["methane", "emissions"],
    "agencies": ["EPA"],
    "documentTypes": ["rule", "proposed-rule"],
    "cfrReferences": ["40 CFR 60", "40 CFR 63"],
    "significantOnly": false,
    "publishedFrom": "30 days",
    "commentOpenOnly": true,
    "maxResults": 100,
    "mode": "monitor",
    "monitorName": "epa-air"
}
```

| Field | Meaning |
| --- | --- |
| `searchTerms` | Words or phrases; a document matches if it contains any of them. |
| `agencies` | Agency names, abbreviations or slugs. A name matches every agency whose name contains it. |
| `documentTypes` | `rule`, `proposed-rule`, `notice`, `presidential-document`. Empty = all. |
| `cfrReferences` | `40` (a whole title) or `40 CFR 60` / `40/60` (one part). |
| `significantOnly` | Only documents marked significant under EO 12866. |
| `publishedFrom`, `publishedTo` | `2026-10-01` or relative (`7 days` = 7 days ago). Default: the last 7 days. |
| `commentOpenOnly` | Only documents whose comment deadline is today or later. |
| `maxResults` | Up to 5,000, newest first (default 100). |
| `mode` | `list` (default) or `monitor`. |
| `monitorName` | Names the snapshot store, so you can edit the filters without losing it. |

### Output example

Real output of a local run on 7 October 2026: EPA proposed rules whose comment period is still open, first four.

| Document | Type | Title | Published | Comments due | CFR |
| --- | --- | --- | --- | --- | --- |
| 2026-20611 | Proposed Rule | Approval and Promulgation of State Air Quality Plans for Designated Facilities and Pollutants; West Virginia ... | 2026-10-07 | 2026-11-06 | 40 CFR 62 |
| 2026-20468 | Proposed Rule | Initial Air Quality Designations for the 2024 Revised Primary Annual F... | 2026-10-06 | 2026-11-05 | 40 CFR 81 |
| 2026-20102 | Proposed Rule | Approval of Implementation Plans for Air Quality Planning Purposes; St... | 2026-10-01 | 2026-11-02 | 40 CFR 52 |
| 2026-20101 | Proposed Rule | Air Plan Approval; OR; Lane County Title 36 Rule | 2026-10-01 | 2026-11-02 | 40 CFR 52 |

The first row in full (abstract shortened):

```json
{
    "documentNumber": "2026-20611",
    "type": "Proposed Rule",
    "action": "Proposed rule.",
    "agencies": ["Environmental Protection Agency"],
    "publicationDate": "2026-10-07",
    "effectiveDate": null,
    "commentDeadline": "2026-11-06",
    "commentPeriodOpen": true,
    "cfrReferences": [{ "title": 40, "part": "62", "text": "40 CFR 62" }],
    "significant": false,
    "abstract": "The Environmental Protection Agency (EPA) is proposing to approve the negative declarations submitted by the West Virginia Department of Environmental Protection (WVDEP) …",
    "htmlUrl": "https://www.federalregister.gov/documents/2026/10/07/2026-20611/approval-and-promulgation-of-state-air-quality-plans-for-designated-facilities-and-pollutants-west",
    "pdfUrl": "https://www.govinfo.gov/content/pkg/FR-2026-10-07/pdf/2026-20611.pdf",
    "docketIds": ["EPA-R03-OAR-2026-6205", "FRL-13584-01-R3"],
    "regulationsGovUrl": null,
    "pages": 3,
    "mode": "list",
    "monitorStatus": "listed"
}
```

#### Monitor mode

`monitorStatus` is `listed` in list mode. In monitor mode it is `baseline` (first run, or after you change the filters) or `new` (not returned before). Checked live on 7 October 2026 with EPA documents of the last 3 days: the first run returned 4 baseline rows, the second returned none (and one free `no-results` row), and after two document numbers were removed from the saved snapshot the third run returned exactly those two as `new`.

### How much does it cost?

This Actor uses **pay per event**:

| Event | Price |
| --- | --- |
| Document returned (one row each) | **$0.001** |
| Info rows, error rows and "no results" rows | **free** |

- 1,000 documents cost **$1**. The default run (50 rows) costs **$0.05**.
- In monitor mode you pay for the rows you get: the baseline once, then only new documents.
- The Federal Register API is free. Apify also charges a tiny standard start fee per run.
- Set **Maximum cost per run** and the Actor stops when it is reached.

### Limitations

- **Only what the Federal Register publishes.** Documents appear on the day of publication; corrections are separate documents.
- **Search is the Federal Register's own full-text search**, which matches the document text, not only the title.
- **Several search terms or CFR references run as separate searches** and are merged (at most 20 combinations).
- **The Federal Register search returns at most 10,000 results** for one query; use a shorter date window for bigger jobs.
- **Monitor mode remembers document numbers, not versions**: a document is returned once. Its list is kept for 90 days.
- `significant` reflects the Unified Agenda marking; most documents are not marked.

### FAQ

#### Is this official data?

Yes. It comes from the Federal Register API run by the Office of the Federal Register (National Archives) and the Government Publishing Office.

#### Do I need an API key?

No.

#### How is monitor mode different from list mode?

List mode returns every matching document each time. Monitor mode remembers the document numbers it has returned (in a named key-value store in your account) and returns only new ones.

#### Can I get rules that change a specific part of the CFR?

Yes: put `40 CFR 60` in `cfrReferences`. You get every document that amends or affects that part.

#### Where is the Regulations.gov link?

`regulationsGovUrl` is filled when the document has a comment page on Regulations.gov; otherwise it is `null`.
