Mid Price API for agents
Mid price = (bid + ask) / 2 for spread-aware marks. Call when normalizing BBO into a single mid for agents. Returns mid price 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.

One command, attributed.
The source header follows this discovery route through challenge, payment and delivery without exposing the buyer or request body.
