How this service works
CNAME record of assets.<domain>: looks up the assets 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 assets without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the CNAME record for assets.<domain> exists, the CNAME target record(s), the TTL value, and the DNS response code (e.g. NOERROR or NXDOMAIN).
Example use cases
CDN origin verification for assets subdomain
“Check if assets.shopify-store-example.com has a CNAME record set up — I want to know what CDN or host it's pointing to.”
Pre-deployment subdomain existence check
“Before I configure the new deployment, can you verify whether assets.mycompany.com already has a CNAME record and what its TTL is?”
Third-party asset host audit
“I'm auditing our domain infrastructure — can you look up the CNAME for assets.brandsite.com and tell me if it exists and where it resolves to?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/assets/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted check on whether assets.<domain> has a CNAME record, without doing broad subdomain enumeration. Ideal for infrastructure audits, deployment verification, or CDN configuration checks where Cloudflare's authoritative DoH resolution is preferred over other resolvers.
Side effects
- Domain does not exist — returns NXDOMAIN response code with no records
- assets subdomain has no CNAME record — exists flag is false
- Invalid domain format provided — malformed query
- Cloudflare DoH unreachable — upstream DNS resolution failure
- Rate limiting or payment failure — request rejected
