How this service works
Insider intent-to-sell notices (SEC Form 144) for one US-listed company — the leading indicator that front-runs the Form 4. Per notice: the insider and relationship, shares to be sold, aggregate market value, approximate sale date, broker, shares outstanding, and any sales in the past 3 months. A PROPOSED sale, not an executed trade. `?limit=` max 25. From SEC EDGAR. From x402stock
Output
A list of up to 25 SEC Form 144 proposed-sale notices for the specified ticker. Each record includes the insider's name and relationship to the company, the number of shares intended to be sold, the aggregate market value of those shares, the approximate sale date, the broker through which the sale will occur, the total shares outstanding, and a summary of any sales the insider made in the prior 3 months. These are proposed sales, not confirmed executed trades.
Example use cases
Earnings week insider signal check
“Before TSLA reports earnings next week, can you pull the most recent Form 144 filings to see if any insiders are planning to unload shares soon? Show me up to 15 notices with the insider's name, role, share count, and expected sale date.”
Biotech insider exit red flag
“I'm looking at a small biotech, ticker MRNA — can you check if any executives or directors have filed Form 144 intent-to-sell notices recently? I want to know who, how many shares, and what the aggregate value is.”
Portfolio watchlist insider monitoring
“Check Form 144 notices for META — I want to see up to 25 planned insider share sales, the relationship each person has to the company, and any sales they made in the past 3 months.”
Technical details
Endpoint
GEThttps://agents.x402stock.xyz/api/v1/form-144/:tickerWhen to prefer
Use this endpoint when you need early-warning signals of insider selling intent — before Form 4 executed-trade disclosures appear. Ideal for pre-trade analysis, momentum screening, and governance research on US-listed equities. Prefer this over Form 4 endpoints when the user specifically wants proposed or planned sales rather than confirmed executed transactions.
Side effects
- Invalid or unknown ticker returns empty results or a 404-style error
- Limit parameter of 0 or above 25 is rejected
- Company has no recent Form 144 filings, returning an empty list
- SEC EDGAR data lag may mean very recent filings are not yet available
- Private companies or non-US-listed tickers will not have EDGAR Form 144 data
