MX Host Parse API for agents
Parse MX preference and host from an MX record string. Call when normalizing DNS MX answers for deliverability logic. Returns preference and host 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.
