How this service works
Momus MLB model: win probabilities for one game from a pitcher-aware Elo (starter FIP/ERA, bullpen, home field) fitted on 7,000+ games, the de-vigged market, the 60/40 blend Momus bets on, fair odds, probable starters. Deterministic, no LLM. Either team name is enough for that team's next game.
Output
Returns win probabilities for both teams, fair odds, de-vigged market odds, the 60/40 model-market blend Momus uses for betting, probable starting pitchers with FIP/ERA metrics, bullpen ratings, and home field advantage adjustments — all deterministically computed from a model trained on 7,000+ games.

Endpoint
GEThttps://x402.momusai.io/mlb?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, pitcher-aware MLB win probability model that blends Elo ratings with live market odds — especially when starter FIP/ERA and bullpen quality matter for the prediction. Prefer it over generic odds APIs when you want fair (de-vigged) probabilities and a model-market blend rather than raw sportsbook lines.
