How this service works
CNAME record of pay.<domain>: looks up the pay 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 pay without enumerating subdomains. $0.01 per lookup.
Output
Returns whether a CNAME record exists for pay.<domain>, the CNAME target hostname it points to, the TTL value in seconds, and the raw DNS response details from Cloudflare's DNS over HTTPS resolver.
Example use cases
Payment subdomain existence check
“Does pay.shopify.com have a CNAME record configured? I want to know if their pay subdomain is active and what it resolves to.”
Verifying payment infrastructure for a domain
“Check if pay.acme.com has a CNAME record — I'm auditing their DNS setup to see whether they have a dedicated payment subdomain.”
Competitive domain research
“I'm researching how various SaaS companies set up payment subdomains — can you look up the CNAME record for pay.notion.so and tell me if it exists and what its TTL is?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/pay/cname?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted check for the pay.<domain> CNAME record specifically, without enumerating all subdomains. Prefer it over full DNS enumeration tools when you only care about the pay host and want a fast, cheap single lookup via Cloudflare DoH. Ideal for payment infrastructure auditing, competitive research, or validating whether a business has a dedicated payment subdomain configured.
Side effects
- Domain does not have a pay subdomain CNAME — returns not found or empty record set
- Invalid or malformed domain name input causes a resolution error
- Cloudflare DoH resolver temporarily unavailable — upstream timeout or failure
- Domain exists but pay host has an A/AAAA record instead of a CNAME — may return empty CNAME result
- Payment of $0.01 USDC fails or is rejected — endpoint returns 402 Payment Required
