## README

### US Congress Stock Trades API

Get US Congress members' financial disclosures and stock trades (member, ticker, transaction type, amount range, and dates), filterable by member, ticker, or date range. Results come newest filing first (by reportedUtc, not tradedUtc), so a recent filing can list trades made years earlier.

#### Request

```bash
curl -X POST "https://api.sandbase.ai/v1/run" \
  -H "Authorization: Bearer $SANDBASE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "congress/trades", "limit": 5}'
```

The result is returned in `outputs[0].data`. Lookups that find nothing fail with a not-found error.

#### Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `endDate` | string | No | Latest transaction date to include, inclusive, in YYYY-MM-DD format (e.g. 2026-06-01). |
| `firstName` | string | No | Filter by the congressional member's first name, case-insensitive partial match (e.g. Nancy). |
| `lastName` | string | No | Filter by the congressional member's last name, case-insensitive partial match (e.g. Pelosi). |
| `limit` | integer | No | Maximum number of results to return (1-25, default 25). You are billed per result returned, so a lower limit costs less. |
| `startDate` | string | No | Earliest transaction date to include, inclusive, in YYYY-MM-DD format (e.g. 2026-01-01). |
| `ticker` | string | No | Filter to transactions involving this stock ticker symbol (e.g. NVDA). |

#### Pricing

Billed at the actual cost of each call: about $0.00181 per result returned, up to $0.0462 per request (about $0.00905 for the request above). A call can cost more when the first data source fails and another one answers. Failed calls and lookups that find nothing are not charged.
