## 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 sec-13f-institutional-holdings-by-ticker-e05b2a99
```

Example prompt: Pull the top institutional holders for NVDA from SEC 13F filings — I want to see which hedge funds and asset managers have the biggest positions ranked by market value.

## When to prefer this

Use this endpoint when you need to identify the largest institutional holders of a specific US-listed stock from real SEC 13F filings. Prefer this over general financial data APIs when you specifically want hedge fund and asset manager ownership data ranked by market value, or when tracking 'smart money' accumulation trends. For combined insider trading + institutional data in one call, consider the Smart Money Bundle sibling endpoint instead.

## Known failure modes

- Invalid or unrecognized ticker returns an error — use a valid US-listed symbol (e.g. AAPL, BRK.B)
- Ticker for a non-US-listed company may return no results or an error
- Newly listed stocks may have no 13F data yet if no filing period has elapsed
- Payment failure (402) if USDC balance is insufficient for the $0.03 per-call fee
- Rate limiting if too many calls are made in a short window
