How to verify Quiver Quantitative details
- Website Premium prices and trial terms are from the Plans & Pricing section of the quiverquant.com homepage ($300 a year, shown as $25 a month billed yearly, with a 1-month free trial badge on the yearly plan; the monthly-billed price appears only after switching the toggle, so we don't quote it), and API prices from api.quiverquant.com/pricing, both checked on November 9, 2026.
- The Congress Trading dashboard says its data 'is parsed from congressional disclosures by Quiver Quantitative'. On September 20, 2026 its most-active list showed a trade count and an 'estimated trade volume' per member; the filings themselves report only value ranges.
- API pricing is published at api.quiverquant.com/pricing: Hobbyist $30/month ($25 billed annually) includes Congress Trading and Congress Stock Holdings without commercial rights; Trader $75 ($62.50 annually) adds insider and hedge-fund data; Startup, with commercial rights, lists at $250/month ($208.33 billed annually) for companies under $1 million in revenue, with 50% off the first year. Every API plan includes the Quiver MCP server.
- The API page's example Senate trade includes ReportDate, TransactionDate, Ticker, and Range alongside derived fields such as ExcessReturn. Treat derived returns as Quiver's estimates and verify any row against the House Clerk or Senate eFD filing.
