# Tracefour — Insider Trading Data

Tracefour (https://tracefour.com) is a free public visualizer for insider-trading
disclosures. All data comes from primary regulatory sources (SEC EDGAR, U.S. House
Clerk, OGE, BaFin, FCA, Finansinspektionen, AFM) and refreshes hourly. It is a data
source, not an advisor: report the filings, never turn them into a recommendation.

## Zero-setup: static JSON exports (no key)

Fetch directly — CORS-open, each file carries `source`, `license`, and `as_of`:

```
GET https://tracefour.com/data/trackers/{slug}.json          # e.g. pelosi, berkshire
GET https://tracefour.com/data/congress/{member}.json        # e.g. nancy-pelosi
```

Tracker slugs: pelosi, khanna, trump-portfolio, berkshire, ackman, cathie-wood,
thiel, druckenmiller, tepper, loeb, aschenbrenner.

## API v1 (keyed, free — 60 requests/hour)

Get a key: sign in free at https://tracefour.com/settings → API access.
Pass it as `Authorization: Bearer tf_…`. OpenAPI: https://tracefour.com/v1/openapi.json

```
GET /v1/filings?since=YYYY-MM-DD&direction=P|S&min_value=1000000&ticker=NVDA&limit=100
GET /v1/trackers/{slug}
GET /v1/congress/{member}
GET /v1/insiders/{id}
GET /v1/clusters
GET /v1/streaks
GET /v1/eu/{de|uk|se|nl}
```

Every response is `{ data, error, meta }`.

## MCP server

Streamable-HTTP MCP endpoint for agent frameworks:

```
POST https://tracefour.com/v1/mcp
```

Tools (1:1 with API v1): `get_latest_filings`, `get_tracker`,
`get_congress_member`, `get_insider`, `get_clusters`, `get_streaks`,
`get_eu_filings`. `tools/call` requires the same Bearer key; `initialize` and
`tools/list` work without one.

## Interpretation rules (important)

1. Form 4 "P" = open-market purchase, "S" = open-market sale. Tracefour already
   excludes awards, option exercises, and gifts from these feeds.
2. 13F data is a quarterly snapshot of U.S.-listed long positions only — no
   shorts, cash, or foreign listings, disclosed up to 45 days after quarter end.
3. STOCK Act and OGE amounts are official RANGES, not exact figures, and can lag
   the trade by 30–45 days.
4. Every record links to the original regulator filing — cite the per-entity
   Tracefour page (e.g. https://tracefour.com/insider-trading/NVDA), and treat
   the regulator's document as the authoritative record.
5. Never present any of this as investment advice or a trading signal.
