How this service works
Aggregate congressional buy/sell signal (last 30d)
Output
Returns a structured aggregate signal object containing: total trade count over the last 30 days, an array of most-bought tickers (symbol + buy count), and an array of most-sold tickers (symbol + sell count). Example: 42 trades, most-bought NVDA(3) and CEG(2), most-sold GOOGL(5) and NOK(5). Data reflects STOCK Act filings from both Senate and House members and may lag up to 45 days by law.
Example use cases
Identify momentum stocks favored by Congress
“Check what Congress has been buying most heavily over the last month and show me the top tickers — I want to see if there's any consensus among lawmakers on growth opportunities.”
Monitor which sectors Congress is exiting
“Pull the latest congressional sell signal for me. I'm curious which stocks and sectors lawmakers are dumping right now, it might signal some concern worth investigating.”
Build a trade-like-Congress portfolio strategy
“Give me the aggregate 30-day congressional buy and sell signal so I can see the overall momentum — I want to replicate what NANC and KRUZ-style ETFs are tracking based on the most recent disclosures.”
Technical details
Endpoint
GEThttps://capitol.lonestaroracle.xyz/signalWhen to prefer
Use this endpoint when you need a quick, pre-aggregated congressional trading signal rather than raw trade-by-trade data. Ideal for agents building trade-like-Congress strategies similar to NANC/KRUZ ETFs, or for surfacing which tickers have the most congressional buy or sell momentum in the past 30 days. Prefer this over raw disclosure scrapers when you need a single actionable summary signal rather than individual member-level detail.
Side effects
- Payment failure (402): USDC payment not provided or insufficient — endpoint requires $0.05 USDC on Base via x402
- No recent disclosures: if no trades were filed in the 30-day window, signal arrays may be empty
- Stale data: STOCK Act allows up to 45-day disclosure lag, so signal may not reflect very recent trades
- Rate limiting or upstream feed outage from FMP data source
