FiatDock

Live Polymarket markets: each outcome's price (the market's implied probability), 24h and total volume, liquidity, closing date and link. Search by topic (bitcoin, fed rates, election…) or send {} for the markets with the most 24h volume. A search with no open market is 404 and not charged. Pay-per-call via x402.
