How this service works
Real insider conviction from SEC Form 4 filings. Classifies every transaction by its one-letter code, so an RSU vest is not reported as an insider buy and the automatic tax withholding that follows is not reported as a sale. Returns only codes P and S — the trades where someone chose to move money at the market price — plus cluster-buy detection when several insiders buy the same issuer within a window. Query by ticker or CIK.
Output
A list of filtered Form 4 transactions classified as genuine open-market buys (code P) or sells (code S), with transaction date, price, shares, insider identity, and role. Also includes a cluster-buy detection signal when multiple insiders buy the same issuer within a short time window.
Example use cases
Conviction insider buy check before earnings
“Check if any TSLA insiders made genuine open-market purchases in the last 60 days — filter out the RSU vests and automatic withholding sales, I only want real conviction buys.”
Cluster buy detection across multiple insiders
“Look at SEC Form 4 filings for AMD from May 1 to August 15 2026 and tell me if several insiders were buying at the same time — that cluster signal matters more to me than individual trades.”
Insider activity lookup by CIK for ambiguous ticker
“The ticker is ambiguous so use CIK 0000320193 — show me all open-market buys and sells filed in the last 90 days, up to 10 filings, no RSU noise.”
Technical details
Endpoint
GEThttps://x402-filings.datalayer.workers.dev/v1/sec/insider-trading?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need signal-pure insider conviction data — open-market buys and sells only — rather than raw Form 4 dumps that mix RSU vests, ESPP purchases, and tax-withholding sales. Prefer this over generic SEC EDGAR scrapers when the goal is to distinguish true insider sentiment from automatic plan-driven transactions, or when cluster-buy detection across multiple insiders is needed for a single issuer.
Side effects
- Missing ticker and CIK returns a validation error — at least one is required
- Invalid or unrecognized ticker returns empty results or a not-found error
- Date range with no filings returns an empty list
- Limit outside 1-25 range may return a parameter validation error
- CIK not zero-padded may still resolve but malformed values will fail
- SEC EDGAR upstream latency or outages may cause delayed or failed responses
