How this service works
CNAME record of portal.<domain>: looks up the portal 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 portal without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the CNAME record for portal.<domain> exists, the CNAME target hostname it points to, the TTL value in seconds, and the DNS response code (e.g. NOERROR or NXDOMAIN).
Example use cases
Verify portal subdomain before onboarding
“Before we start the client onboarding, check whether acmecorp.com has a portal subdomain set up in DNS — specifically the CNAME record and where it points.”
Audit competitor portal presence
“I want to know if our competitor shopify.com has a portal subdomain configured — look up the CNAME record for portal.shopify.com and tell me what it resolves to.”
Validate SaaS customer DNS setup
“Our customer says they've configured their portal subdomain — can you verify that portal.customerdomain.io has a CNAME record and check what it points to and the TTL?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/portal/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, low-cost existence check for the portal subdomain of a specific domain without enumerating all subdomains. It is ideal for validating customer DNS configurations, auditing whether SaaS portals are set up, or reconnaissance tasks focused on the common 'portal' host pattern. Prefer it over generic CNAME endpoints when you specifically care about the portal subdomain.
Side effects
- Domain does not exist — NXDOMAIN response with no records returned
- portal subdomain has no CNAME record configured — empty record set
- Malformed or missing domain input parameter causes request failure
- Cloudflare DoH upstream timeout or error
- Rate limiting or payment failure returns 402
