## 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 agenttoll-insider-cluster-brief-307de771 -d '<json body>'
```

Example prompt: Check the latest SEC insider filing clusters for NVDA and tell me whether multiple insiders are buying or selling together — give me a verdict on whether it's worth watching.

## When to prefer this

Choose this endpoint when you need a synthesized, verdict-driven summary of insider cluster activity from SEC filings rather than raw filing data. Ideal for quick due diligence, pre-trade research, or building watchlists around insider sentiment signals. Prefer this over raw SEC EDGAR queries when you want clustered analysis rather than individual filing lookup.

## Known failure modes

- Invalid or unrecognized ticker symbol returns empty clusters array
- No recent filings available for the requested company or period
- Payment failure via x402 protocol blocks the request
- Rate limiting if too many calls are made in quick succession
- Ambiguous company name without ticker may return incorrect data
