Catch the moment someone becomes an insider. This tracker scans SEC EDGAR for new Form 3 filings — the initial statement filed within 10 days of a person becoming an officer, director, or 10%+ beneficial owner — and returns each new filing as pay-per-result JSON, $0.10 per filing. No Bloomberg Terminal seat, no insider-data subscription.

A Form 3 is the very first filing a person makes when they become an insider of a public company — a newly appointed director or officer, or a new holder crossing the 10% beneficial-ownership threshold. It is the leading edge of insider activity: before anyone files a Form 4 to report a trade, they must first appear on a Form 3 to declare they are an insider at all. This actor is a filing-discovery feed: it reads the official SEC EDGAR ownership-form index for new Form 3 filings, optionally narrows by keyword, and returns each as a clean structured row with company, ticker, CIK, form type, filing date, accession number, and a direct EDGAR document URL. It tells you a new insider has appeared and points you straight to the filing — it does not parse the Form 3 XML, so it does not extract the reporting owner's name, role, or the initial holdings table. For those details, open the linked document.

Why use this

Insider and ownership intelligence is gated behind expensive terminals and specialist data vendors. The underlying source they all parse is the same public Form 3 filings this actor surfaces — and Form 3, specifically, is where a new 10% owner or new officer/director first appears on EDGAR, before any Form 4 trade exists to flag them.

This actor solves the discovery problem. It queries EDGAR full-text search for the Form 3 ownership form, lets you AND an optional exact-phrase keyword onto the form filter (to target a company or sector), de-duplicates, and returns a clean feed keyed to the primary EDGAR document. Run it daily and you have a live early-warning system for new insider filings — for cents per filing instead of a terminal seat. When you need the ownership amounts, the documentUrl takes you straight to the source document.

What you get

Every record is structured JSON with the fields below — filing-discovery metadata, populated from the EDGAR index:

• companyName — the issuer the new insider is reporting against, as registered with the SEC
• ticker — exchange ticker symbol when EDGAR maps the issuer to one (null for issuers without a mapped symbol)
• cik — the issuer's SEC Central Index Key
• formType — the ownership form (3 — initial beneficial ownership)
• filedDate — the date the filing was accepted by EDGAR (YYYY-MM-DD)
• accessionNumber — the EDGAR accession number for the filing
• primaryDocument — the primary document filename
• documentUrl — direct link to the primary Form 3 document on sec.gov, where the reporting person, role, and initial holdings appear
• filingIndexUrl — link to the filing's EDGAR index page

The actor returns the filing and a link to it — not the parsed ownership amounts. The schema is stable across runs, so you can load straight into Snowflake, BigQuery, Postgres, or your CRM without re-mapping each refresh.

Use cases

• Activist-stake early warning — Spot a new 10% beneficial owner the day the Form 3 hits EDGAR — often the first public footprint of an activist or strategic accumulating a position before a 13D campaign goes loud.
• Governance / IR monitoring — Track new officers and directors at peer companies; a cluster of new officer/director Form 3s against one issuer signals a board refresh or post-acquisition reconstitution.
• "New insiders this week" feeds — News and research desks building a recurring list of newly registered insiders with direct EDGAR links.
• M&A and proxy monitoring — New 10% owners and new officer/director slates often accompany takeovers and going-private deals; catch the sudden new large holders early.
• Pipeline seed — Get the filing URLs, then fetch the holdings detail downstream from the linked documents.

from apify_client import ApifyClient
client = ApifyClient("YOUR_TOKEN")
run = client.actor("nexgendata/sec-form-3-new-insider-tracker").call(run_input={
"forms":"3",
"daysBack":7,
"maxResults":300,
})
for item in client.dataset(run["defaultDatasetId"]).iterate_items():

Schedule it daily via Apify's built-in scheduler and dedupe on accessionNumber into your warehouse. Wire a webhook to fire a Slack or n8n alert whenever a new 10% owner or a cluster of new officer/director filings lands against a watched issuer.

Pricing

This actor runs on Apify's pay-per-event (PPE) model — you pay only for results, not run-time:

• $0.10 per filing record pushed to your dataset
• A negligible per-actor-start charge

No subscriptions, no seat licences, no per-CPU-second billing.

Why pay-per-event beats time-based pricing

• Predictable — cost equals filing count, known before the run.
• Failure-safe — if EDGAR changes its HTML and a run returns 0 rows, you pay 0.
• Easy to attribute — 1 filing = 1 unit of cost, so per-strategy or per-desk accounting is trivial.

FAQ

Q: What is SEC Form 3?

A: The initial statement of beneficial ownership, filed within 10 days of becoming an officer, director, or 10%+ owner of a public company.

Q: How do I find newly appointed insiders?

A: This tracker lists new Form 3 filings in your look-back window with direct EDGAR links, so you see the moment a new insider registers.

Q: What's the difference between Form 3 and Form 4?

A: Form 3 = initial ownership when you become an insider; Form 4 = ongoing transaction reports. Use the Form 4 actors for trades.

A: No — it returns the filing and a link to it. For the holdings table, open the linked Form 3 document at documentUrl.

Q: How fast do Form 3s appear?

A: As soon as EDGAR indexes them; the tracker scans by filing date and picks up new filings each run.

Q: What output formats are supported?

A: JSON, JSONL, CSV, and Excel via Apify's dataset export, plus webhook delivery.

Compliance & legal

• The actor reads public, unauthenticated SEC EDGAR pages — the same ownership-form index any browser can open, with no login.
• It identifies itself to the SEC with a compliant User-Agent (set yours via userAgentContact) per the SEC fair-access policy, and paces requests politely.
• NexGenData is not affiliated with, endorsed by, or sponsored by the U.S. Securities and Exchange Commission. "EDGAR" is a service of the SEC.

• You are responsible for ensuring downstream use complies with applicable securities laws and the SEC's terms of access.
