How this service works
CNAME record of img.<domain>: looks up the img 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 img without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the img.<domain> CNAME record exists, the CNAME target(s) it points to, the TTL value, and the DNS response code (e.g. NOERROR or NXDOMAIN) as answered by Cloudflare DoH.
Example use cases
Verify CDN image subdomain config
“Does shopify.com have an img subdomain configured? Check the CNAME record for img.shopify.com to see where it points.”
Check competitor image infrastructure
“I want to know if stripe.com uses a dedicated img subdomain — look up the CNAME for img.stripe.com and tell me what it resolves to and the TTL.”
Validate domain setup before launch
“Before we go live, can you confirm that img.acmecorp.com exists and has a valid CNAME record pointing somewhere? Just do a quick DNS lookup.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/img/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to check whether the img subdomain of a given domain has a CNAME record configured, without running a full subdomain enumeration. Ideal for quick, targeted infrastructure checks on a single common hostname pattern via Cloudflare's DoH resolver.
Side effects
- NXDOMAIN returned when img subdomain does not exist for the given domain
- Invalid or malformed domain name causes lookup failure
- Cloudflare DoH upstream timeout or unavailability
- Domain exists but has no CNAME record type (only A or other records)
- Rate limiting or payment failure for $0.01 per call charge
