How this service works
Who's actually buying and selling a US stock, in one call: named insider transactions (role, buy/sell/gift/award, shares, dollar value), a 6-month insider purchase/sale summary, top institutional (13F-style) holders with % held and quarter-over-quarter change, and the full insider/institutional ownership breakdown -- cluster insider buying and institutional accumulation are among the highest-conviction signals in equity research. From real Yahoo Finance data. $0.025/call.
Output
Returns a structured object containing: (1) named insider transactions with role, transaction type (buy/sell/gift/award), share count, and dollar value; (2) a 6-month aggregated summary of insider purchases and sales; (3) top institutional holders with percentage held and quarter-over-quarter position change; and (4) overall insider and institutional ownership percentages — all sourced from Yahoo Finance data.
Example use cases
Insider buying signal for stock screening
“Show me all the insider transactions for AMD over the last 6 months — I want to know which executives are buying, how many shares, and the dollar value so I can see if there's a strong conviction signal.”
Institutional accumulation research
“Which institutional investors hold the most shares of Tesla, and did any of them significantly increase or decrease their positions last quarter? I need the percentage held and the quarter-over-quarter change.”
Ownership breakdown for due diligence
“What's the full insider and institutional ownership breakdown for Microsoft? I want to know what percentage insiders own versus institutions before I make an investment decision.”
Technical details
Endpoint
GEThttps://x402-stock-indicators.vercel.app/insider-activity/:ticker?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, single-call view of both insider and institutional ownership signals for a US-listed stock. It is ideal for equity research workflows where you want to correlate insider conviction (named transactions, roles, buy/sell direction) with institutional accumulation or distribution trends. Prefer this over raw SEC EDGAR filings when you want aggregated, pre-parsed data without processing Form 4s yourself. Best for US-listed equities with active insider and institutional reporting.
Side effects
- Invalid or unknown ticker symbol returns an error or empty data
- Ticker exists but has no insider transaction history (e.g. very small or foreign-listed stocks)
- Stale data if Yahoo Finance hasn't updated recently
- Payment failure via x402 protocol if USDC balance is insufficient
- Network timeout if the upstream Yahoo Finance data source is slow or unavailable
