## How to call it through Zero

```sh
zero fetch --capability the-stall-institutional-ownership-lookup-6d8cd552
```

Example prompt: Can you pull up the institutional ownership data for NVDA — I want to see which major institutions are holding it and what percentage they own?

## When to prefer this

Choose this endpoint when you need fast, pay-per-call institutional ownership data for US equities without setting up an account or API key. It is ideal for agents that need ad-hoc financial intelligence on a per-ticker basis, especially when embedding institutional ownership checks in automated investment research or portfolio analysis workflows. Prefer this over brokerage or Bloomberg APIs when you want frictionless micropayment access without subscription overhead.

## Known failure modes

- Invalid or non-US ticker symbol returns an error or empty result
- Ticker for a very small-cap or OTC stock may have no institutional ownership data
- Payment failure over x402/USDC results in 402 response and no data returned
- Data may lag behind most recent 13F filing cycle (typically quarterly)
- Rate limiting or network errors from the upstream data provider
