  "description": "Constant-product AMM output amount for a given input size. Call when simulating x*y=k swaps offline from reserves you already know. Returns amount out and new reserves 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.",
