How this service works
CNAME record of help.<domain>: looks up the help 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 help without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the help.<domain> CNAME record exists, the full DNS record data including the canonical target host, and the TTL value for the record.
Example use cases
Verify help desk subdomain setup
“Does help.shopify.com have a CNAME record set up? If so, what does it point to and what's the TTL?”
Audit competitor help subdomain
“Can you check whether help.notion.so has a CNAME record configured and tell me where it resolves to?”
Validate new domain help routing
“I just set up a CNAME for help.mynewstartup.io — can you confirm the DNS record exists and show me what it's pointing to?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/help/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted check for the CNAME record of specifically the 'help' subdomain of a given domain, without enumerating all subdomains. Ideal for validating help desk or documentation platform routing (e.g. Help Scout, Zendesk) and for infrastructure audits where you want to confirm a specific well-known host is properly configured.
Side effects
- Domain does not have a help subdomain CNAME (record not found, existence=false)
- Invalid or malformed domain name input
- Cloudflare DoH upstream timeout or resolution failure
- Domain does not exist at all (NXDOMAIN)
- Payment not included or insufficient (x402 payment required)
