## How to call it through Zero

```sh
zero fetch --capability insider-congressional-trading-signal-9e8b3945
```

Example prompt: What's the insider and congressional trading signal for NVDA over the past 90 days? I want to know the composite score, whether insiders are net buyers, and if any House members have traded it recently.

## When to prefer this

Use this endpoint when you need a pre-computed, fused signal combining both SEC Form-4 insider filings and congressional STOCK Act disclosures in one score, rather than querying raw filings yourself. Prefer it over raw EDGAR scraping when you want normalized flags (cluster buy, unusual volume, congressional activity) with direct transaction references rather than building your own aggregation logic.

## Known failure modes

- Unknown ticker or CIK returns empty or error response
- No transactions in the specified window returns a low/neutral score with no flags set
- Invalid date format for startdt/enddt causes a 400 error
- EDGAR or STOCK Act data source temporarily unavailable causes a 503
- Very recent filings may not yet be indexed, causing disclosure lag to appear higher

## How this service works

Composite deterministic insider and congressional signal for one ticker over a window. Fuses SEC Form-4 insider transactions and US House STOCK Act trades into a 0-100 signal score plus flags: net insider buying, cluster buy across distinct insiders, unusual volume, congressional activity, and average disclosure lag. Each flag references the underlying transactions.

## Output

Returns a 0-100 composite signal score plus boolean flags for: net insider buying, cluster buy (multiple distinct insiders buying), unusual volume, congressional activity, and average disclosure lag. Each flag includes references to the underlying SEC Form-4 and STOCK Act transactions that triggered it.
