How this service works
CNAME record of blog.<domain>: looks up the blog 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 blog without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the blog.<domain> CNAME record exists, the actual CNAME record value(s) it holds, and the TTL (time-to-live) of the record as answered by Cloudflare DNS-over-HTTPS.
Example use cases
Verify blog subdomain before launch
“We're about to launch a marketing blog — can you check if blog.acmecorp.com has a CNAME record configured and what host it points to?”
Audit competitor blog infrastructure
“I want to know if blog.shopify.com has a CNAME record and where it's pointing — can you look that up for me?”
Debug missing blog subdomain
“Our blog at blog.mystore.io seems unreachable — can you check if the CNAME record exists and what the TTL is?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/blog/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, targeted check of whether a specific domain has a blog subdomain CNAME record, without running a full subdomain enumeration. Prefer this over general DNS resolvers when you want Cloudflare DoH as the resolver and need a simple existence check with TTL. Ideal for pre-launch validation, infrastructure auditing, or monitoring a single well-known subdomain.
Side effects
- Domain does not exist — returns no records found
- blog subdomain has no CNAME record configured — returns empty or NXDOMAIN response
- Invalid domain format supplied — may return error or empty result
- Cloudflare DoH temporarily unavailable — lookup may fail or timeout
- Domain has blog subdomain but as A/AAAA record, not CNAME — returns no CNAME records
