## 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 capitolflow-congressional-stock-trades-d3a35dc5
```

Example prompt: Pull the latest congressional stock trades for NVDA — I want to see which senators and representatives have been buying or selling it and get the overall 30-day Congress buy/sell signal.

## When to prefer this

Use this endpoint when you need structured, pay-per-call access to US congressional STOCK Act trade disclosures without scraping dashboards. Ideal for agents building trading signals around legislative behavior (similar to NANC/KRUZ ETF strategies), researching which lawmakers traded specific stocks, or monitoring the aggregate buy/sell sentiment from Congress. Prefer over manual dashboard browsing or expensive data subscriptions for single-query use cases.

## Known failure modes

- Invalid or unrecognized ticker symbol returns empty results
- Data is inherently lagged up to 45 days by law — recent trades may not yet be disclosed
- Payment failure via x402 if USDC balance insufficient
- Rate limiting if limit parameter is invalid or too large
- No trades found for a given ticker if Congress members haven't traded it recently

## How this service works

US congressional (Senate+House) stock trades; ?symbol= for a ticker

## Output

Returns a list of recent congressional STOCK Act trade disclosures including member name, party, district, ticker symbol, transaction type (buy/sell), dollar-amount range, transaction date, disclosure date, and owner. When querying by ticker, filters to trades for that specific symbol. Also returns a 30-day aggregate signal showing the most-bought and most-sold tickers across both chambers.

 "description": "US congressional stock trades made agent-callable — the Senate and House STOCK Act disclosures that retail traders track (the 'trade like Congress' signal behind ETFs like NANC/KRUZ), served as a pay-per-call x402 endpoint instead of a human dashboard. Returns recent disclosed trades across both chambers (member, party district, ticker, buy/sell, dollar-amount range, transaction + disclosure dates, owner), a by-ticker lookup (who in Congress traded a given symbol), and an aggregate 30-day buy/sell signal (most-bought / most-sold tickers). Data is lagged by design (STOCK Act allows up to 45 days to disclose). $0.05 in USDC on Base via x402. Source: FMP Senate/House disclosure feeds, self-indexed. Companion to InsiderFlow (corporate insiders)."
