How this service works
TXT record of auth.<domain>: looks up the auth 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 auth without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the TXT record for auth.<domain> exists, the record values if present, the TTL, and the raw DNS response data retrieved via Cloudflare DoH.
Example use cases
Verify auth subdomain DNS setup
“Check whether auth.acmecorp.com has any TXT records in DNS — I'm trying to confirm the auth subdomain is properly configured before we go live.”
Security audit of auth endpoint presence
“I'm auditing our client's domain securityfirm.io — can you look up the TXT record for its auth subdomain and tell me if it exists and what it says?”
Pre-deployment DNS sanity check
“Before I deploy our authentication service, can you confirm that auth.startupapp.dev has a TXT record set in DNS and what the TTL is?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/auth/txt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, targeted check for the TXT record of the 'auth' subdomain specifically, without needing to enumerate other subdomains. Prefer this over generic DNS lookup tools when you want a pre-scoped, single-call existence check for auth.<domain> via Cloudflare DoH with a simple pay-per-use pricing model.
Side effects
- Domain does not exist — NXDOMAIN response indicating the apex domain itself is not found
- auth subdomain has no TXT record — empty or NOERROR with no answer section
- Malformed domain input causing resolver error
- Cloudflare DoH upstream timeout or unavailability
- Rate limiting or payment failure (x402) blocking the request
