How this service works
Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.
Output
Returns a JSON object containing: a list of recent insider transactions (date, shares, value, transaction type, insider name and role), a list of top institutional holders (holder name, shares held, percent of float, recent percent change, reporting date), major holders breakdown (institution count, insider percent held, institution percent held, float percent), and a 6-month insider purchase/sale summary (total buy/sell shares and transaction counts, net shares purchased, and total insider shares held).
Example use cases
Monitoring insider selling before earnings
“Check TSLA's insider activity — have any executives or officers been selling shares in the last six months, and what's the net insider position?”
Institutional ownership due diligence
“I'm researching MSFT as an investment — can you show me the top institutional holders, what percentage of the company they own, and whether they've been increasing or decreasing their stakes?”
Screening stocks with heavy insider buying
“Pull the insider purchase summary for AMD and tell me if insiders have been net buyers recently — I want to know how many shares were purchased vs sold over the past six months.”

Endpoint
GEThttps://x402-stock-indicators.vercel.app/insider-activity/%7Bticker%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need insider trading disclosures, institutional holder composition, or insider sentiment (net buyer/seller) for a publicly traded US stock. It is especially useful for fundamental analysis, pre-investment due diligence, or detecting unusual insider activity. Prefer this over general quote endpoints when ownership structure and insider behavior are the primary signals of interest, and prefer it over SEC EDGAR direct lookups when you want pre-aggregated, structured data without parsing raw filings.
Side effects
- Invalid or unknown ticker symbol returns an error or empty result
- Ticker not covered by Yahoo Finance data source returns no data
- Payment failure or insufficient USDC balance results in 402 response blocking the call
- Network or upstream data provider outage returns a 5xx error
- Delisted or OTC tickers may return incomplete institutional data
