Cian DNS & Email Auth Audit$0.01 / callcian-x402.netlify.app ↗
DnsEmailSpfDmarcSecurity

DNS and email-authentication audit for one domain: A/AAAA presence, NS count and whether the nameservers share a /24, MX (including a null MX), SPF (missing, multiple, +all, ~all, ?all), DMARC (missing, p=none, no rua, partial pct), a DKIM selector probe, CAA, and whether the zone is DNSSEC-signed. Read entirely over DNS-over-HTTPS, so nothing is sent to the target host. Every finding carries a stable id, a severity and a fix.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
