Binary EV (Buy Yes)
Expected value of buying binary YES at market_price under true_prob. Call when deciding whether a YES buy has positive EV before size. Returns EV per $1 notional on YES 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.
One-command purchase
Run it from an agent.
No account or API key. AgentCash reads the 402 challenge, pays no more than the declared cap, retries the request and returns the result.
