How this service works
SEC Form 4 insider trading API: the latest insider transactions (open-market buys and sales, grants, option exercises and more) from EDGAR, refreshed about once a minute, with ticker, insider, role, transaction code, shares, price, dollar value, shares owned after, Rule 10b5-1 flag and the filing link. Filters: ticker, insider, code, minimum value, date range, role, 10b5-1 plan. Plus cluster buys (2+ insiders buying within 7 days). REST + MCP server. Information only, not investment advice.
Output
A JSON array of insider transaction records pulled from SEC EDGAR, each containing ticker symbol, insider name, insider role (director/officer/10% owner), transaction code (P=buy, S=sale, etc.), number of shares, price per share, total dollar value, shares owned after the transaction, whether the trade was under a Rule 10b5-1 plan, filing date, trade date, and a direct link to the SEC filing. Also supports cluster buy results grouping 2+ insiders buying the same stock within 7 days.
Example use cases
Spot cluster buying at a single stock
“Check if multiple insiders have been buying shares of TSLA in the past 7 days — I want to see any cluster buys and the details of each transaction including who bought, how many shares, and at what price.”
Screen market-wide discretionary insider buys
“Show me the 50 largest open-market insider purchases across any company in the last 14 days, worth at least $1 million each, and exclude any trades made under a 10b5-1 plan so I only see discretionary buying.”
Track a specific executive's trading activity
“Look up all recent SEC Form 4 transactions filed by Elon Musk across any ticker in the last 30 days — I want to see every transaction type including grants and option exercises, not just buys and sells.”

Endpoint
GEThttps://insidewell-api.cybermax-tools.workers.dev/x402/api/trades?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need near-real-time SEC Form 4 insider transaction data refreshed approximately every minute, with rich filtering (ticker, role, transaction code, minimum dollar value, 10b5-1 flag, date range) and built-in cluster buy detection. Prefer it over static financial data APIs when freshness and EDGAR-sourced accuracy matter, or when you specifically need to identify coordinated insider buying patterns.
