Live game pairings between Polymarket and Kalshi
Cross-references currently-live Polymarket games against currently-live Kalshi games, grouped by a Kalshi-league -> Polymarket-sport crosswalk and matched via a multi-step heuristic (ticker-code match, team-name/alias substring match, derived-code prefix match, letter-subset fallback). Price scale note: Kalshi market prices in the kalshiMarkets array are rescaled to a 0-100 range (not the 0-1 scale used elsewhere in this API) to match a legacy response shape. Falls back to a recent last-known-good snapshot if the live Kalshi data is unavailable. Responses are cacheable.
