## How to call it through Zero

```sh
zero fetch --capability insider-congressional-trading-signal-b423fe1f
```

Example prompt: What's the insider and congressional trading signal for NVDA over the last 90 days? I want to see the score, whether insiders are net buyers, if there's cluster buying, and any congressional activity.

## When to prefer this

Choose this endpoint when you need a single deterministic numeric signal that fuses both corporate insider (SEC Form-4) and US congressional (STOCK Act) trading activity for a ticker, especially when you want actionable flags like cluster buying or unusual volume rather than raw transaction data. Prefer over raw SEC EDGAR scraping when you need a pre-computed, normalized score ready for downstream decision-making or alerting.

## Known failure modes

- Unknown ticker or CIK returns empty or error response
- Date range with no transactions returns score of 0 with all flags false
- Invalid date format causes 400-level error
- Very recent transactions may not yet be indexed in SEC EDGAR
- Congressional disclosures may lag by weeks under STOCK Act rules, reducing recency

## 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

A JSON object containing: a composite signal score from 0 to 100 (higher = stronger insider/congressional buy signal), boolean flags for net insider buying, cluster buying across distinct insiders, unusual volume, and congressional activity, average disclosure lag in days, and the underlying SEC Form-4 and STOCK Act transactions that support each flag.
