How this service works
Schedule 13D/13G filings — triggered when a holder crosses 5% of a class — disclosing beneficial-ownership and activist stakes in a US-listed company, from SEC EDGAR. Per filing: the reporting person, filer-reported percent of class (can be <5% if held via derivatives), shares, voting/dispositive power, and (for 13D) the activist intent. `?type=13D|13G|all`, `?limit=` max 25. From x402stock
Output
A list of up to 25 Schedule 13D/13G filings for the requested ticker, each including the reporting person's name, the filer-reported percent of class (which may be below 5% if derivatives are involved), total shares held, voting power, dispositive power, and (for 13D filings) the activist intent statement, all sourced from SEC EDGAR.
Example use cases
Activist investor detection for a stock
“Has any activist investor filed a Schedule 13D on Salesforce? Show me up to 10 recent 13D filings and what their stated intentions are.”
Institutional ownership threshold check
“Who has filed Schedule 13G disclosures on Palantir — meaning passive holders over 5%? Give me the most recent 15 filings with the filer name and percentage held.”
M&A research on beneficial owners
“I'm researching Southwest Airlines — can you pull both 13D and 13G SEC filings to see who the major beneficial owners are and whether anyone has crossed the 5% threshold recently?”
Technical details
Endpoint
GEThttps://agents.x402stock.xyz/api/v1/beneficial-ownership/:ticker?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to identify beneficial owners holding 5%+ of a US-listed company's shares, detect activist investor positions via 13D filings, or surface passive institutional stakes via 13G filings — all sourced directly from SEC EDGAR. Prefer this over general institutional holdings databases when regulatory-grade disclosed ownership at the 5% threshold is required, especially for M&A research, activist tracking, or governance analysis.
Side effects
- Invalid or unknown ticker returns empty results or 404
- Limit exceeds 25 returns a validation error
- No 13D/13G filings on record returns an empty array
- EDGAR data lag may mean very recent filings are not yet indexed
- Derivatives-based holdings may show percent below 5% threshold, which can be confusing
