# Get latest ATP singles match probabilities

GET https://api.datafortennis.com/v2/live/matches/{matchId}/prediction

Explicit predictions entitlement required. Reads a stored projection without computing history or invoking a model. Probabilities are ordered like player_ids and sum to one. They are null while warming, pending, stale, suspended or unavailable. Poll without reusing an Idempotency-Key for a new state. A replay that no longer represents a current unexpired prediction is rejected. League scope is ATP Tour singles, initially normal 250/500/1000 formats. Shadow access is restricted to qualified operator credentials.
