Bankroll Fraction Stake API for agents
Stake size from bankroll and fraction (Kelly or fixed-f). Call when turning a fraction into dollars to risk this bet. Returns stake amount 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.
