## 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 insider-institutional-data-61931a6a
```

Example prompt: Pull up the full insider and institutional ownership picture for NVDA — I want to see who's been buying, any cluster insider activity, and which institutions hold the most shares with their quarter-over-quarter changes.

## When to prefer this

Choose this endpoint when you need a comprehensive, single-call view of both insider transactions and institutional ownership for a US-listed stock — particularly useful for equity research conviction signals like cluster insider buying or institutional accumulation. Prefer over building separate SEC EDGAR + 13F scrapers when speed and cost efficiency matter.

## Known failure modes

- Invalid or unknown ticker symbol returns an error
- Ticker has no insider transaction data available (e.g. very small or foreign-listed companies)
- Yahoo Finance data temporarily unavailable causing upstream errors
- Payment not fulfilled resulting in 402 response
- Rate limiting or timeout on high-demand tickers

## 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 named insider transactions (role, transaction type, shares, dollar value), a 6-month insider purchase/sale summary, top institutional (13F-style) holders with percentage held and quarter-over-quarter change, and a full insider/institutional ownership breakdown for the requested ticker.
