## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability financial-data-x402-insider-activity-0a6f2f91
```

Example prompt: Pull the latest insider activity for AAPL — I want to see recent insider buys and sells, who the major institutional holders are, and the overall insider ownership breakdown.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
