How this service works
SEC Form 3 filings reporting initial statements of beneficial ownership of securities. Filed by corporate insiders (directors, officers, and 10%+ shareholders) when they first acquire a position. Can't find what you're looking for? POST feedback to /feedback, no charge.
Output
Returns a list of SEC Form 3 filing records including filing date, form type (3 or 3/A), issuer company details, reporting owner identity and CIK, and beneficial ownership information. Results can be filtered by ticker, issuer CIK, owner CIK, filing date range, and form type, and sorted and paginated as needed.
Example use cases

Technical details
Endpoint
GEThttps://agent.massive.com/stocks/filings/vX/form-3When to prefer
Use this endpoint when you need to identify when corporate insiders (directors, officers, or 10%+ shareholders) first disclosed a beneficial ownership position in a company via SEC Form 3 filings. Prefer this over Form 4 when you specifically want initial ownership statements rather than changes in ownership. Ideal for monitoring new insider entries, corporate governance research, and compliance tracking.
