How this service works
Initial beneficial-ownership holdings parsed from SEC Form 3 filings, the first report an insider files on becoming a director, officer, or 10% holder. Each holding carries the security, shares owned, direct or indirect ownership, and derivative terms. Complements Form 4 transactions. ?limit= filings (default 5). Sourced from SEC EDGAR. From x402stock, a market & economic data API (x402, USDC).
Output
A list of parsed Form 3 filings (up to the requested limit, default 5, max 25), each containing the reporting insider's identity, the security name, number of shares owned, whether ownership is direct or indirect, and any derivative instrument terms such as options or warrants. Data is sourced directly from SEC EDGAR.
Example use cases
New board director ownership check
“Can you show me the most recent Form 3 filings for Apple? I want to know what shares each newly appointed director or officer declared owning when they first took their position.”
10% holder initial stake investigation
“Look up SEC Form 3 filings for Tesla and show me up to 15 of the most recent ones — I'm trying to see what any new major 10% holders reported as their initial beneficial ownership.”
Insider ownership baseline for M&A research
“Fetch the initial insider ownership filings from SEC EDGAR for JPM — I need the Form 3 data so I can compare what insiders originally held versus what they've traded since.”
Technical details
Endpoint
GEThttps://agents.x402stock.xyz/api/v1/form-3/:tickerWhen to prefer
Use this endpoint when you need the initial ownership baseline that an insider declared upon becoming a director, officer, or 10% shareholder — i.e., the starting point before any Form 4 transactions. It complements Form 4 data by establishing what insiders held at inception. Prefer this over general SEC filing endpoints when you specifically need Form 3 data rather than ongoing transaction history.
Side effects
- Invalid or unknown ticker symbol returns an error or empty result set
- Ticker with no Form 3 filings on record returns an empty array
- Limit parameter outside allowed range (must be 1–25) returns a validation error
- SEC EDGAR source unavailability may cause delayed or failed responses
- Network or payment (x402/USDC) failure prevents the request from completing
