How this service works
SEC Form 144 insider sale notices of a US stock: proposed sales by officers, directors and 10% holders over days=1-365 - planned sale value, sellers, relationship and dates. Use to see insider sales before they happen.
Output
A JSON list of SEC Form 144 notice records for the requested ticker, each containing the seller's name, their relationship to the company (officer, director, 10% holder), the planned sale value, proposed sale date, and other relevant filing details. Returns a 404 if the ticker is unknown, and no charge is made in that case.
Example use cases
Pre-trade insider selling check
“Before I buy more Apple stock, can you check if any insiders — officers, directors, or big holders — have filed Form 144 sale notices in the last 60 days?”
Earnings season insider activity scan
“I'm researching JPMorgan ahead of earnings — can you pull all SEC Form 144 proposed insider sales for JPM over the past 30 days so I can see if executives are offloading shares?”
Long-term insider trend monitoring
“Can you get me all Form 144 insider sale filings for Coca-Cola over the past year? I want to see the full picture of who's been selling, how much, and when.”
Technical details
Endpoint
GEThttps://api.marketintelligenceapi.com/api/v1/sec/form-144/:symbol?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need SEC Form 144 pre-sale notices filed by corporate insiders of US-listed companies. It is the right choice when you want advance warning of planned insider sales before they execute, as opposed to post-trade Form 4 disclosures. Prefer this over generic news or sentiment APIs when regulatory filing data is required for investment due diligence or compliance monitoring.
Side effects
- 404 Not Found – ticker symbol is not recognized or has no SEC filings (no charge applied)
- Invalid days parameter – outside the 1–365 range returns a validation error
- Payment failure – x402 micropayment not completed, request blocked
- Rate limiting – too many calls in a short period
- Empty result set – ticker is valid but no Form 144 notices exist in the look-back window
