DNS Caa Policy Check API for agents
DNS Caa Policy Check: checks whether a certificate authority identifier is allowed by CAA records using only bounded caller-supplied values. Call when you need a bounded dns caa policy check result before deciding whether a certificate authority is allowed by caller-supplied CAA records. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for DNS Caa Policy Check 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.
