POST /api/v1/x402/multi-outcome-kelly

live

Proportional Kelly-like stakes across exclusive outcomes. Call when allocating bankroll across multi-outcome prediction markets. Returns stakes and fractions per outcome 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.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
