Prediction Market ROI API for agents
ROI from entry price and resolution payout on a binary share. Call when post-resolution performance of a prediction-market fill. Returns roi and profit 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.
