Searches open prediction markets on Polymarket (real money, USDC) and Manifold (play money) by keywords, with optional closing-date window and minimum volume. Each row: venue, question, outcomes with prices (implied probability), volume with its unit (USD or mana), liquidity, close time and link. Results alternate between venues; up to 50 rows. Information only, not financial advice. Usually answers in about 8 s, up to 15 s on slower calls; allow a 30 s timeout.
