How this service works
A record of checkout.<domain>: looks up the checkout host under the domain you give (A via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like checkout without enumerating subdomains. $0.01 per lookup.
Output
Returns whether checkout.<domain> has an A record in DNS, the resolved IP address(es), the TTL, and the DNS response code indicating existence or NXDOMAIN/NOERROR status.
Example use cases
Verify checkout subdomain before launch
“Before we go live, can you confirm that checkout.mybrand.com has an A record set up and tell me what IP it points to?”
Debug missing checkout page
“Our customers are getting errors on checkout — can you check if checkout.acmecorp.com is resolving correctly in DNS right now?”
Competitor infrastructure recon
“I want to know if competitor.com has a dedicated checkout subdomain set up — can you look up whether checkout.competitor.com has an A record?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/checkout/a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap existence-and-resolution check specifically for the checkout subdomain of a domain, without enumerating all subdomains. Prefer it over generic DNS tools when you already know you want the checkout host and want a pre-scoped, single-query answer via Cloudflare DoH.
Side effects
- Domain does not have a checkout subdomain (NXDOMAIN response)
- Invalid or malformed domain input
- Cloudflare DoH upstream timeout or unavailability
- Payment failure for the $0.01 USDC per lookup fee
