Kelly Fraction API for agents
Kelly fraction from win probability and net payoff odds b. Call when bankroll sizing for repeated bets with known edge (advisory). Returns full Kelly fraction clamped to [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.
