Api Endpoint

Expected Log Growth

Approx expected log bankroll growth for a binary bet fraction. Call when comparing bet sizes by growth rate under true_prob (advisory). Returns expected log growth 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.
