How this service works
Recent SEC Form 4 insider filings (officers, directors, 10% owners reporting trades) for one company CIK, from EDGAR's public submissions index. Lists filings with dates and links; transaction amounts are not parsed.
Output
Returns a JSON object with the company name, CIK, total count of filings returned, the source URL on SEC EDGAR, a timestamp of when it was checked, and an array of filing objects each containing the form type, filed date, accession number, document filename, and full URL to the filing on SEC.gov.
Example use cases
Monitor executive insider trades
“Get me the last 10 SEC Form 4 filings for Microsoft — CIK 789019 — so I can see what insiders have been buying or selling.”
Research insider activity before earnings
“Pull the 5 most recent Form 4 filings for Nvidia (CIK 1045810) — I want to see if any executives have been dumping shares ahead of earnings.”
Due diligence on a small-cap stock
“Fetch the latest 20 SEC Form 4 disclosures for this company with CIK 0001318605 so I can review all recent insider ownership changes.”
Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/finance/sec-form4?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable SEC Form 4 insider trading filings for a known public company identified by CIK, without signing up for an API key. Ideal for agents doing financial due diligence, monitoring insider activity, or enriching equity research workflows. Prefer this over direct EDGAR scraping when you want a clean JSON response and pay-per-call pricing with no subscription.
Side effects
- Invalid or non-existent CIK returns empty results or error
- CIK with no Form 4 filings returns empty filings array
- Limit out of range (outside 1-20) may cause validation error
- SEC EDGAR temporarily unavailable causes upstream fetch failure
- Payment failure results in no charge and no response data
