Order Book Mid From Levels

api.delx.ai · x402

Compute mid price from bid/ask top-of-book levels. Call when you have L1 bid and ask and need a mid for marks. Returns mid, spread_abs, and spread_bps 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.
