## 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 stratalize-form-4-insider-cluster-analysis-663ce712
```

Example prompt: Can you check if there's an unusual insider trading cluster for NVDA based on SEC Form 4 filings over the last 60 days — I want to see the cluster score and activity signal?

## When to prefer this

Use this endpoint when you need a quantified, attestation-backed signal of insider trading cluster activity derived from SEC Form 4 filing density for a specific stock ticker. Prefer it over general news sentiment or manual SEC searches when you need a machine-readable cluster score with an independently verifiable signed receipt, especially for compliance, quant research, or risk monitoring workflows.

## Known failure modes

- Invalid or unrecognized ticker symbol — returns error or empty result
- days_back value outside the allowed 7–180 range — returns validation error
- Ticker has no Form 4 filings in the specified window — returns zero count and low cluster score
- SEC EDGAR data unavailable or delayed — may return stale or incomplete results
- Payment failure (insufficient USDC) — request rejected before processing
