## 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 df-market-intelligence-insider-cluster-buying-signal-0d1ab97f
```

Example prompt: Show me stocks where at least 3 different insiders bought shares on the open market in the last 30 days, ranked by the number of buyers and total dollar value — I want the strongest clustered insider buying signals.

## When to prefer this

Choose this endpoint when you need a high-signal insider sentiment screen specifically based on coordinated multi-insider buying rather than individual Form 4 transactions. It is superior to raw insider transaction feeds when you want to filter out noise and focus only on stocks with multiple distinct insiders acting in the same direction within a defined window — a widely recognized strong bullish signal.

## Known failure modes

- No clusters found for the given parameters — try widening the day window or lowering min_insiders
- Invalid days value (must be 1–90) returns an error
- Invalid min_insiders value (must be 2–10) returns an error
- Data freshness lag if SEC Form 4 filings are delayed
- Payment failure if x402 USDC balance is insufficient

## How this service works

Stocks where several different insiders bought shares on the open market in the same window — one of the strongest public insider signals. Ranked by number of insiders and dollar value.

## Output

A ranked list of US stocks where multiple insiders made open-market share purchases within the specified time window, ordered by number of distinct insider buyers and total dollar value of purchases. Each record includes the stock ticker, insider count, and aggregate purchase value.
