How this service works
Market-wide recent insider intent-to-sell notices (SEC Form 144) across all issuers
Output
Returns SEC Form 144 filing data for the queried company, including proposed insider stock sales with details such as filer identity, relationship to the company, number of shares proposed for sale, estimated sale date, broker/dealer information, and the nature of the securities involved.
Example use cases
Insider selling signal before earnings
“Check for any Form 144 filings on NVDA in the past 30 days — I want to know if any executives or directors have proposed selling shares ahead of next week's earnings report.”
Due diligence on management conviction
“Before I invest, can you pull SEC Form 144 data for Palantir to see how much insider selling has been proposed recently and who the sellers are?”
Monitoring activist short thesis
“I'm researching a potential short — get me the Form 144 filings for AMC Entertainment so I can see if insiders are lining up to dump shares.”
Technical details
Endpoint
GEThttps://agents.x402stock.xyz/api/v1/form-144?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need SEC Form 144 insider proposed-sale data specifically — it is distinct from Form 4 (reported completed transactions) and is the right choice when monitoring early signals of planned insider selling. Prefer this over general SEC EDGAR scraping when you need a clean, agent-ready JSON response without parsing HTML filings manually, and when paying per-request in USDC is acceptable.
Side effects
- Invalid or unrecognized ticker symbol returns an error or empty result
- No Form 144 filings on record for the specified company returns empty dataset
- Payment failure in USDC via x402 results in request rejection
- Malformed request body returns a validation error
- Endpoint returns stale data if SEC EDGAR pipeline is delayed
