OddsPapi Real-Time Odds WebSocket API

OddsPapi Real-Time Odds WebSocket API is a websocket from OddsPapi (oddspapi.io) providing sports data. OddsPapi aggregates real-time sports betting odds from 300-350+ bookmakers (including sharp books Pinnacle, Singbet, SBOBet) and pushes them over a low-latency WebSocket feed. A Polymarket bot can use the sharp-book line consensus to anchor and front-run sports game-outcome and in-game market prices, since regulated sportsbook lines move faster and more efficiently than prediction-market odds.
