Every Polymarket market you need in one table: probability, every outcome's price, bid and ask, 24-hour and 7-day change, volume, liquidity, close date, resolution status and, once settled, the result. Search by keyword or category, paste event links, add daily price history, and schedule it to get an alert row whenever a market moves by the points you choose.
Built for traders and forecasters, journalists and newsletters, quant and research teams, app and bot builders, and AI agents.
What you get
One row per market: a yes/no market, or one outcome of a multi-outcome event (each candidate, each rate decision, each team).
