DNS MX Priority Sort API for agents
DNS MX Priority Sort: sorts MX exchanges by preference while preserving equal-priority order using only bounded caller-supplied values. Call when you need a bounded dns mx priority sort result before choosing an MX exchange from caller-supplied preference records. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for DNS MX Priority Sort as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.
