How this service works
SEC Form 4 filings reporting changes in beneficial ownership of securities. Filed by corporate insiders (directors, officers, and 10%+ shareholders) within two business days of a transaction. Can't find what you're looking for? POST feedback to /feedback, no charge.
Output
A list of SEC Form 4 filing records including details on the reporting owner, issuer company, ticker symbols, filing date, form type (4 or 4/A), and beneficial ownership transaction data. Results are pageable up to 10,000 records and sortable by filing date.
Example use cases
Detecting executive stock sell-off
“Show me all Form 4 filings for NVDA from the past two weeks sorted by filing date descending — I want to see if any executives or directors have been selling shares recently.”
Tracking a known insider's activity
“Look up all SEC Form 4 filings submitted by owner CIK 0001234567 over the past six months, sorted by filing date descending, up to 200 results.”
Screening for insider buying signals
“Get me the latest 100 Form 4 filings across any ticker filed since 2024-01-01 where the form type is '4', sorted by filing date ascending, so I can look for unusual insider buying patterns.”
Technical details
Endpoint
GEThttps://agent.massive.com/stocks/filings/vX/form-4When to prefer
Use this endpoint when you need structured, filterable access to SEC Form 4 insider ownership change filings — especially when filtering by ticker, CIK, or date range. Prefer this over general SEC EDGAR search when you need clean, machine-readable data with consistent pagination and sorting. Choose this over Form 3 filings when you need changes in ownership rather than initial ownership statements.
Side effects
- Invalid date format returns a 400 error — dates must be YYYY-MM-DD
- Unknown or invalid CIK returns empty results rather than an error
- Requesting limit above 10,000 returns a validation error
- Malformed ticker symbol may return no results if not matched in EDGAR data
- Rate limiting or payment failure for x402 micropayment may block the request
