DNS Cname Chain Check
DNS Cname Chain Check: DNS Cname Chain Check checks a caller-supplied CNAME chain for loops and hop budget from bounded caller-supplied values without an external provider. Call DNS Cname Chain Check before trusting a caller-supplied CNAME chain that may loop or exceed hop budget. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for DNS Cname Chain Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. 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.
