How this service works
Use to see insider sales before they happen. Returns SEC Form 144 notices of proposed sales by officers, directors and 10% holders of a US-listed company over days=1-365: planned sale value, sellers, relationship and dates.
Output
A structured list of SEC Form 144 notices for the requested ticker covering the specified date window, including each proposed seller's name, their relationship to the company (officer, director, or 10%+ holder), planned sale value, and relevant filing/sale dates.
Example use cases
Pre-trade insider sentiment check
“Before I add to my NVDA position, check if any officers or directors have filed Form 144 notices to sell shares in the last 14 days — I want to know who, how much, and their role.”
Earnings-week insider sell monitoring
“It's earnings week for Tesla — can you pull all SEC Form 144 proposed sales by TSLA insiders filed in the last 7 days so I can see if executives are planning to cash out?”
Compliance desk insider activity alert
“Run a check on Form 144 filings for AAPL over the past 90 days and give me a breakdown of each seller's name, relationship to the company, and the planned sale amount.”
Technical details
Endpoint
GEThttps://api.marketintelligenceapi.com/api/v1/sec/form-144/NVDA?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need advance visibility into planned insider stock sales via SEC Form 144 filings for a specific US-listed company. It is distinct from Form 4 insider transaction endpoints (which report completed trades) — Form 144 captures proposed future sales before execution, giving earlier signal. Prefer this over general insider-trading APIs when you specifically need pre-sale disclosure data for officers, directors, or 10%+ shareholders.
Side effects
- Invalid or unrecognized ticker symbol returns an error or empty result
- days parameter out of range (outside 1–365) returns a validation error
- No Form 144 filings exist for the symbol in the requested period — returns empty list
- Rate limit or payment failure (x402) blocks the response
- Ticker is not a US-listed equity (e.g. a crypto symbol) may return no results or an error
