## 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 institutional-ownership-intelligence-the-stall-intuitek-8bdf1654
```

Example prompt: Pull a full institutional ownership report for NVDA — give me the top 20 holders with their share counts and values, plus the overall breakdown of institutional versus insider ownership and float size.

## When to prefer this

Use this endpoint when you need structured institutional ownership data for a US-listed equity — particularly when you want fund-level detail (top holders, shares, values) alongside aggregate metrics (% institutional, % insider, float, concentration) without signing up for a brokerage data API or paying for a Bloomberg terminal. Ideal for investment research agents, equity screening workflows, and due-diligence automation that needs ownership context on demand with micropayment access (no API key required).

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Non-US equity tickers (e.g. foreign-listed stocks) may not be supported
- Limit parameter out of range (below 1 or above 30) returns a validation error
- Stale data possible if underlying data source has not recently refreshed holdings
- Payment failure on Base mainnet (insufficient USDC, wrong network) blocks the request
- Unknown mode enum value returns a validation error

## Output

Returns structured JSON with institutional ownership data for the requested ticker. In 'holders' mode: a ranked list of up to 30 institutional funds with shares held and USD position value. In 'summary' mode: aggregate metrics including percent institutional, percent insider, float size, and concentration score. In 'full' mode: both datasets combined in a single response.
