POST /api/v1/x402/binary-edge

live

Edge = true_prob − market_price for a binary contract. Call when ranking prediction-market opportunities by model edge. Returns signed edge in probability units 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.
