## 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-radar-13f-institutional-holdings-rollup-fb33a669
```

Example prompt: Pull the top 13F institutional holdings rollup from Insider Radar — show me the most widely held tickers, the filer roster, and holder counts, limited to the top 50 results.

## When to prefer this

Use this endpoint when you need a pre-aggregated, ranked rollup of institutional 13F holdings rather than per-filing or per-fund detail. Ideal for quickly identifying the most institutionally popular tickers, scanning the full filer roster, or checking holder counts across the top 300 names without parsing raw SEC EDGAR data yourself. Prefer this over direct SEC data sources when you need fast, structured, ready-to-use institutional sentiment signals.

## Known failure modes

- Stale data flag set to true if underlying 13F data has not been refreshed recently
- Sample flag set to true if serving demo/partial data rather than full dataset
- Limit parameter exceeding 1000 returns validation error
- Network or upstream data provider unavailability may cause timeout or empty response
- Data may lag official SEC 13F filing deadlines by weeks given regulatory reporting cadence

## How this service works
