## 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 stablejack-institutional-holdings-filing-retrieval-7e3c3279 -d '<json body>'
```

Example prompt: Pull the institutional holdings filing data for institution CIK 0001350694 for Q3 2023 — I want to see what positions they reported to the SEC that quarter.

## When to prefer this

Choose this endpoint when you need programmatic access to SEC institutional holding filings (13F data) for a specific fund identified by CIK, for a defined year and quarter. It is particularly useful for agents conducting investment research, tracking smart money flows, or building fund analysis pipelines, and is preferable to scraping SEC EDGAR directly due to its structured, agent-ready output and pay-per-call model.

## Known failure modes

- Invalid or non-existent CIK returns an error or empty result
- Filing not yet available for a future or very recent quarter
- Incorrect quarter format causes a parameter validation error
- Institution did not file for the specified period, resulting in no data returned
- Network or upstream data source timeout returns a service error
