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
A JSON object containing: a list of dated insider transactions (buyer/seller name, position, transaction type, shares, value, price per share), a list of top institutional holders (name, shares, value, percent held, percent change), a major holders breakdown (institutions count, insider percent held, institutional percent held), and an insider purchases summary with net shares purchased, buy/sell transaction counts, and total insider shares held — all as of a recent date.
Example use cases
Tracking executive stock sales
“Show me all recent insider transactions for NVDA — specifically whether executives have been buying or selling, and how many shares changed hands in the last 6 months.”
Institutional ownership research
“Who are the biggest institutional holders of Microsoft right now, and what percentage of the float do institutions control?”
Insider sentiment signal for trading
“I'm evaluating Tesla as a potential investment — can you pull the insider purchase vs sale ratio and net shares purchased over the last 6 months to see if insiders are bullish or bearish?”
Technical details
Endpoint
GEThttps://x402financialdata.com/insider-activity/%7Bticker%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need SEC-style insider transaction data and institutional ownership breakdowns for a US-listed stock without setting up API keys or subscriptions — ideal for pay-per-call agent workflows using x402/USDC micropayments on Base or Solana. Prefer this over subscription-based financial data APIs when cost per call matters and queries are infrequent or ad hoc.
Side effects
- Invalid or unknown ticker symbol returns empty or error response
- Ticker with no SEC-reported insider activity may return empty transaction list
- Service unavailable or payment failure via x402 protocol returns 402 or 5xx
- Stale data if upstream financial data provider hasn't refreshed recently
- Malformed ticker input (e.g. lowercase or extra characters) may not resolve correctly
