Brier score for a probabilistic forecast vs binary outcome. Call when scoring prediction calibration on resolved markets. Returns brier score in [0,1] as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
