Order Book Imbalance API for agents
Book imbalance (bid_size-ask_size)/(bid_size+ask_size). Call when sizing or signal needs L1 size imbalance. Returns imbalance in [-1,1] 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.
