How this service works
Insider buying vs selling for a US company from its latest Form 4 filings: open-market buys, sells, clusters.
Output
Returns a structured object including: company name, CIK, total open-market buys and sells in USD, a list of recent trades with owner, role, date, price, share count, USD value, and whether the trade was a 10b5-1 plan; distinct buyer count; number of Form 4 filings read; planned-sale share percentage; cluster thresholds; a human-readable summary; a verdict on insider sentiment; and any reasons or caveats behind the verdict.
Example use cases
Pre-investment insider sentiment check
“Before I buy into Palantir, can you check what insiders have been doing with their shares over the last 90 days? I want to know if they're buying or selling in the open market and whether there's a cluster of buyers.”
Screening for insider buying clusters
“I'm looking at small-cap biotech stocks — can you check insider activity for SAVA over the last 60 days and tell me how many distinct insiders have been buying and what the sentiment verdict is?”
Distinguishing planned vs discretionary insider sales
“There's been a lot of insider selling at Salesforce lately — can you pull the Form 4 data for the last 180 days and tell me what percentage of those sales were planned 10b5-1 trades versus discretionary open-market sells?”
Technical details
Endpoint
GEThttps://company-enrichment.x402tookit.com/sec-insider-activity?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, pre-analyzed view of insider buying and selling signals from Form 4 filings — especially when you want open-market trade separation, 10b5-1 plan detection, cluster signals, and a ready-made verdict rather than parsing raw SEC EDGAR filings yourself. Prefer this over a general SEC filings endpoint when the specific question is about insider sentiment or executive conviction.
Side effects
- Unknown ticker or CIK returns null or empty company field
- No Form 4 filings found in the lookback window returns zero trades and a degraded flag
- Invalid 'days' parameter outside 7–180 range may return an error or be clamped
- Company with very sparse SEC filings may return degraded: true with limited data
- Rate-limit or payment failure returns a 402 response requiring payment
