How this service works
CNAME record of sso.<domain>: looks up the sso host under the domain you give (CNAME via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like sso without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the CNAME record for sso.<domain> exists, the CNAME target(s) it points to, and the TTL value. If the record does not exist, the response indicates absence. Delivered via Cloudflare DoH resolution.
Example use cases
Verify SSO infrastructure before integration
“Before we integrate with Acme Corp's SSO, can you check if sso.acmecorp.com has a CNAME record and where it points?”
Security audit of company SSO endpoints
“I'm auditing our vendors — can you look up whether sso.stripe.com has a CNAME configured and what its TTL is?”
Detect SSO subdomain takeover risk
“Can you check if sso.abandonedstartup.io has a CNAME record? I want to see if it's dangling and potentially vulnerable to subdomain takeover.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/sso/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, lightweight check on whether a specific domain has an SSO subdomain configured via CNAME, without doing full subdomain enumeration. Ideal for security audits, vendor assessments, or pre-integration checks where you only care about the sso host specifically. Prefer this over generic DNS tools when you want a pay-per-lookup, agent-friendly API backed by Cloudflare DoH for reliability.
Side effects
- Domain does not exist — returns no record found
- sso subdomain has no CNAME record (may have A or other record types instead)
- Cloudflare DoH query timeout or upstream DNS failure
- Invalid domain format provided as input
- Payment of $0.01 USDC not fulfilled — request rejected
