Email Syntax Check API for agents
Validate basic email syntax and split local/domain. Call when preflight before MX/DNS steps. Returns ok, local, domain 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.
