Binary EV (Buy Yes) API for agents
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.
Intent to transaction
One command, attributed.
The source header follows this discovery route through challenge, payment and delivery without exposing the buyer or request body.
