Polymarket Crypto Up or Down Markets (Open)

omnial/polymarket-crypto-up-down-markets

Returns 50 open Polymarket crypto Up or Down markets on several coins, with spans such as hourly and daily, the ones closing furthest out first: each market's title, market and event slugs, condition ID, coin, timeframe, status, Up and Down prices, total volume, liquidity, and start and end times. Takes no input. Most of these markets opened days ahead and have little or no trading yet; the ones closing soonest are not included.
