How this service works
CNAME record of beta.<domain>: looks up the beta 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 beta without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the CNAME record for beta.<domain> exists, the actual CNAME target record(s), the TTL value, and the DNS response code (e.g. NOERROR or NXDOMAIN), as resolved by Cloudflare DNS over HTTPS.
Example use cases
Verify beta environment DNS setup
“Check whether beta.stripe.com has a CNAME record — I'm trying to confirm their beta environment is live and what host it aliases to.”
Pre-deployment subdomain validation
“Before we go live, can you confirm that beta.myapp.io has a valid CNAME entry in DNS so I know the subdomain is properly configured?”
Competitor infrastructure recon
“Does beta.competitor.com have a CNAME record? I want to see if they're running a beta environment and what hosting provider it points to.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/beta/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted check for whether a beta subdomain CNAME record exists under a given domain without running a full subdomain enumeration. It is ideal for pre-deployment validation, infrastructure audits, and checking whether a domain has a staging/beta environment configured, leveraging Cloudflare's reliable DoH resolver.
Side effects
- Domain does not exist — NXDOMAIN response with no records
- beta subdomain has no CNAME record (may have A or other record types instead)
- Invalid domain format causes lookup failure
- Cloudflare DoH upstream timeout or unavailability
- Payment failure prevents lookup from being executed
