MEV Sandwich Loss Upper Bound API for agents
Upper-bound CPMM price impact loss for size vs reserves. Call when pre-trade MEV/slippage stress without mempool access. Returns impact_fraction and loss_notional 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.
