Tournament bracket with live cross-provider prices per tie
Builds a tournament bracket for league. Bracket structure and results are sourced from third-party sports-data providers depending on the league. Each tie/match is enriched with live prices from Polymarket, Kalshi (authenticated API), and Predict.fun where a corresponding market can be matched. format=symmetric (default) returns a left/right bracket converging on final, with an optional thirdPlace match and, for format=groups-then-knockout, a groups stage with standings tables. format=left-to-right instead returns all rounds in leftRounds with an empty rightRounds. winner is always null — this endpoint never resolves a champion. Responses are briefly cached.
