How this service works
List issuers where 3+ distinct officers or directors bought within a week — returns combined buy USD, insider count and names per issuer. A derived cluster signal no other API sells as one call; use as a high-conviction insider screen.
Output
A JSON object containing the as_of timestamp, the window in days, and an array of cluster records. Each record includes the issuer's CIK, ticker, company name, number of distinct insiders who bought, their names, combined buy USD, number of filings, and the timestamp of the most recent filing.
Example use cases
Daily high-conviction insider screen
“Show me all companies where at least 3 officers or directors bought shares within the past week — I want the combined buy amount and the names of each insider per company.”
Tighter cluster filter for quant model
“Find insider buy clusters from the last 14 days but only flag companies where at least 5 distinct insiders bought — give me the tickers, total USD purchased, and insider names.”
Weekly watchlist for concentrated insider activity
“Every Monday I want a list of stocks that had coordinated insider buying last week — at least 3 buyers, within a 7-day window, sorted by total dollars purchased.”
Technical details
Endpoint
GEThttps://answerpool.io/v1/sec/insider/clusters?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pre-computed, market-wide signal of coordinated insider buying — specifically when you want companies where multiple distinct insiders bought within a short window, without having to aggregate raw transactions yourself. It is the only single-call API that delivers this cluster-level aggregation. Prefer it over the raw insider screen endpoint when conviction level (number of distinct buyers) matters more than individual transaction details.
Side effects
- No clusters found for the given parameters returns an empty clusters array with count 0
- Invalid days value outside 1-30 range returns a validation error
- Invalid min_insiders value outside 2-10 range returns a validation error
- Stale or delayed SEC EDGAR ingestion may cause recent filings to be missing from results
- Rate limiting or payment failure returns a 402 response requiring USDC payment
