DNS SOA Serial Compare API for agents
DNS SOA Serial Compare: DNS SOA Serial Compare compares SOA serials with 32-bit wraparound ordering from bounded caller-supplied values without an external provider. Call DNS SOA Serial Compare before deciding which SOA serial is newer under 32-bit wraparound. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for DNS SOA Serial Compare 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.
