Spread Percent API for agents
Bid–ask spread as percent of mid for cross-asset compare. Call when comparing liquidity across price levels and assets. Returns spread percent of mid 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.
