How this service works
TXT record of support.<domain>: looks up the support host under the domain you give (TXT via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like support without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the support.<domain> TXT record exists, the content of any TXT records found, and the TTL value, as resolved by Cloudflare DNS over HTTPS.
Example use cases
Verify support subdomain DNS setup
“Check if stripe.com has a TXT record under its support subdomain — I want to know if it exists, what the record contains, and what the TTL is.”
Audit competitor customer support infrastructure
“Look up the TXT record for the support subdomain of shopify.com using Cloudflare DoH and tell me whether it's configured and what it says.”
Validate domain support host before migration
“Before we migrate our helpdesk, can you check whether acme.com currently has a TXT record on its support subdomain and what TTL is set?”

Use this endpoint when you need a quick, targeted check of whether the support subdomain of a given domain has TXT records configured, without doing full subdomain enumeration. Ideal for infrastructure audits, helpdesk verification, or domain reconnaissance focused specifically on the support host via Cloudflare DoH.
