Live prediction-market odds from Polymarket — list the top active markets by vol
Live prediction-market odds from Polymarket — list the top active markets by volume, or search by keyword. Each result has the question, outcomes with current prices (implied probabilities), 24h/total volume, liquidity, and resolution date. No API key. Great for agents tracking real-world event probabilities (elections, crypto, sports, econ). Pass params as query (GET) or a JSON body (POST).
