Binary Fair Price API for agents
Map a true probability into a binary contract fair price in [0,1]. Call when pricing yes/no markets from your probability model. Returns fair price in [0,1] 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, attributed.
The source header follows this discovery route through challenge, payment and delivery without exposing the buyer or request body.
