How this service works
Form 144 filings by ticker — SEC notices of PROPOSED insider sales, filed BEFORE the Form 4 that reports the executed trade: who intends to sell, units, the filer's own market-value estimate, broker, approximate sale date and Rule 10b5-1 plan dates. The earliest public read on insider selling intent; a notice is not a completed trade and may never be executed. Latest 20 notices in a 90-day lookback. Public-domain SEC EDGAR. $0.005 per call.
Output
Returns a JSON object with: a list of up to 20 Form 144 notices (filed within the past 90 days) including seller details, security class, units to be sold, filer's market-value estimate, broker, approximate sale date, and Rule 10b5-1 plan adoption date where applicable; a summary with total notice count, distinct sellers, total units, aggregate market value in USD, amendment count, and date range; coverage metadata (truncation flag, lookback days, candidates found); and a generatedAt timestamp with a methodology link.
Example use cases
Pre-earnings insider selling check
“Before NVDA's earnings next week, can you check if any insiders have recently filed Form 144 notices to sell their shares? I want to know how many are planning to sell and the total market value involved.”
10b5-1 plan tracking for activist monitoring
“I'm tracking institutional signals on TSLA — can you pull Form 144 filings and tell me how many of the proposed sales are under a 10b5-1 plan versus discretionary?”
Insider selling alert for a watchlist stock
“I have AMD on my watchlist — have any officers or directors filed Form 144 notices to sell in the last 90 days? Give me the seller count, total units, and the earliest and latest approximate sale dates.”
Technical details
Endpoint
GEThttps://x402.ottoai.services/form-144-filingsWhen to prefer
Choose this endpoint when you need the earliest available public signal of insider selling intent — before a Form 4 is filed confirming an executed trade. Ideal for pre-trade monitoring, 10b5-1 plan tracking, and alerting workflows. Use this over Form 4 lookups when you want to detect proposed (not yet completed) insider transactions. Covers the most recent 90-day window with up to 20 notices.
Side effects
- Invalid or unrecognized ticker symbol — returns empty or error response
- Ticker has no Form 144 filings in the 90-day lookback — returns notices array empty with zeroed summary
- SEC EDGAR data temporarily unavailable — degraded flag set in meta
- Ticker resolves to a non-US-listed security with no EDGAR record
