How this service works
Search US SEC filings by keyword: institutional holdings (13F), insider transactions (Form 4), 8-K/10-K/10-Q filings, XBRL financials, full-text EFTS hits, litigation and administrative proceedings. Returns filer or company, form type, filing date, and a provenance URL per match. For financial research, compliance, and due-diligence agents.
Output
Returns a list of matched SEC filings, each with the filer or company name, form type (e.g. 13F, Form 4, 10-K, 8-K), filing date, and a provenance URL linking to the original document on SEC EDGAR or EFTS.
Example use cases
Compliance screening for material weakness risks
“Search SEC filings for 'material weakness' across the last two years and show me which companies have disclosed control deficiencies — I need the company name, form type, filing date, and the link to each disclosure so I can flag them for our compliance team.”
Tracking insider transactions at target companies
“Look up Form 4 filings for executives at Tesla and show me recent insider stock transactions — I need to see who's buying or selling, when they filed it, and links to the actual documents so we can monitor for any red flags before we invest.”
Due diligence on institutional ownership patterns
“Search for 13F filings mentioning our acquisition target and show me which major hedge funds and institutional investors hold positions — I need the filer names, filing dates, and links to the actual holdings reports so I can understand the shareholder base.”
Technical details
Endpoint
GEThttps://api.osf-master-server.com/x402/sec/filings/:queryWhen to prefer
Use this endpoint when an agent needs to search across multiple SEC form types simultaneously using a single keyword, company name, ticker, CIK, or subject (e.g. 'material weakness'). Prefer over direct EDGAR queries when provenance-stamped, agent-ready responses with normalized metadata are needed for financial research, compliance screening, or due-diligence workflows.
Side effects
- No filings found for the given keyword — returns empty results
- Ambiguous query matching too many filings — may require more specific keyword such as CIK or ticker
- Query string missing or malformed — returns 400-level error
- Payment not received or insufficient — returns 402 Payment Required
- SEC EDGAR or EFTS upstream unavailable — returns 503 or timeout
