## When to prefer this

Use this endpoint when you need structured, filterable access to US congressional stock trade disclosures sourced directly from STOCK Act PTR filings. Prefer this over manual PDF searches or scraping the House Clerk/Senate eFD websites directly. Best suited for agents tracking political trading activity, researching specific tickers for congressional activity, monitoring compliance lag, or building political transparency dashboards.

## Known failure modes

- No results returned when filter combination matches zero trades (empty array, total=0)
- Invalid transaction type value returns an error or empty result
- Date format not in YYYY-MM-DD causes a parsing error
- Ticker symbol not found in PTR filings returns empty results
- Handwritten/scanned reports may not be included in results if not yet parsed
- Offset beyond total count returns empty results

## How this service works

Search individual US Congress member stock trades, parsed from STOCK Act Periodic Transaction Reports into clean rows. Filter by member name (q, e.g. "Pelosi"), ticker (e.g. NVDA), transaction type (purchase | sale | exchange | partial_sale), 2-letter state, chamber, or transaction-date range (dateFrom/dateTo). Each trade returns the member + state/district, owner (self/spouse/joint/dependent), ticker + asset description, buy/sell, the disclosed dollar RANGE (amountMin/amountMax — disclosures are ranges, not exact), the transaction date, the disclosure date, days-to-disclose (compliance lag), and a link to the source filing PDF. The envelope total is the full count matching your filter — so ticker=NVDA&type=purchase counts who bought NVIDIA. Amounts are ranges by law; trades are disclosed up to 45 days after they happen (current-to-the-filing). Coverage: US House + Senate e-filed PTRs; scanned/handwritten reports are parsed separately. Data: US House Clerk / US Senate eFD (public domain). Cross-ref /api/gov/congress-filings for the raw filing index.

## Output

A paginated JSON envelope with total match count and an array of trade records, each containing: member name, state/district, owner type (self/spouse/joint/dependent), ticker symbol, asset description, transaction type (purchase/sale/exchange/partial_sale), disclosed dollar range (amountMin/amountMax), transaction date, disclosure date, days-to-disclose compliance lag, and a URL to the original source filing PDF.
