How this service works
A record of pay.<domain>: looks up the pay 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 pay without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the A record for pay.<domain> exists, any resolved IPv4 addresses, and the TTL of the record as reported by Cloudflare's DNS-over-HTTPS resolver.
Example use cases
Verify payment subdomain before integration
“Before we start integrating with acme.com's payment portal, can you check if pay.acme.com actually resolves — does it have a valid A record and what IP does it point to?”
Check competitor payment infrastructure
“I want to know if shopify.com has a dedicated pay subdomain set up — can you look up the DNS A record for pay.shopify.com and tell me what you find?”
Debug missing payment page DNS
“Our customers are saying pay.mystore.com isn't loading — can you check if the DNS A record for pay.mystore.com exists and what it resolves to so I can tell if it's a DNS problem?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/pay/a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted existence check for the 'pay' subdomain of a specific domain without enumerating all subdomains. Prefer this over general DNS tools when you specifically care about payment-related subdomain infrastructure and want Cloudflare DoH resolution with minimal cost ($0.01 per lookup).
Side effects
- Domain does not have a pay subdomain — returns no records found
- Invalid or malformed domain name provided — may return an error or empty result
- Cloudflare DoH upstream timeout or unavailability — request may fail
- Rate limiting or payment failure — endpoint returns 402 if payment is not processed
