How this service works
Schedule 13D/13G beneficial-ownership & activist stakes filed on a company (5%+ trigger)
Output
A JSON object containing the company name, CIK, and an array of parsed Schedule 13D/13G filings. Each filing includes the schedule type, form, filing and event dates, CUSIP, security class, accession number, URL to the EDGAR filing, whether it is an amendment, and an array of reporting persons with their percent of class owned, aggregate shares, sole/shared voting power, sole/shared dispositive power, citizenship, and entity type. For 13D filings, the activist purpose/intent field is also included.
Example use cases
Activist investor alert on a stock
“Has any activist investor filed a Schedule 13D on Walt Disney (DIS) recently? I want to know who it is, how many shares they hold, and what their stated purpose is.”
Institutional 13G ownership check
“Show me the most recent 13G passive ownership filings for Apple (AAPL) — who are the largest institutional filers and what percentage of shares does each one hold?”
M&A signal detection
“Look up recent 13D filings for U.S. Steel (X) — I want to see if any strategic buyer or activist has crossed the 5% ownership threshold and what purpose they declared.”
Technical details
Endpoint
GEThttps://agents.x402stock.xyz/api/v1/beneficial-ownership/{ticker}?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, parsed beneficial ownership data directly from SEC EDGAR for any US-listed company. Prefer it over general SEC full-text search when you specifically need 13D/13G data with per-person voting/dispositive breakdowns and activist intent. It is especially useful for activist investing research, M&A signal detection, large shareholder monitoring, and regulatory compliance checks. It covers both passive (13G) and activist (13D) filings and supports filtering by type.
Side effects
- Invalid or unrecognized ticker symbol returns an error or empty result
- Ticker with no 13D/13G filings returns an empty filings array
- Unstructured filings (structured: false) may lack parsed reporting-person fields
- Derivative-based holdings may show percent_of_class below 5% despite triggering the threshold
- limit parameter above 25 is rejected
- Newly filed documents may have a short lag before appearing in EDGAR index
