Get Outcomes By Predexon Id

Overview

Given a canonical Predexon outcome identifier, return every venue listing for that outcome. This is the primary lookup used by the order router to answer: “Which venues offer this same tradeable side, and what’s the venue-native identifier on each?” A predexon_id is canonical at the outcome level. The same outcome across Kalshi, Polymarket, Predict.fun, and other venues shares the same predexon_id when matched.
