How this service works
TXT record of portal.<domain>: looks up the portal 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 portal without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the portal.<domain> subdomain exists in DNS, along with any TXT record values and their TTL as resolved by Cloudflare DNS-over-HTTPS. If the subdomain does not exist, reports non-existence.
Example use cases
Verify portal subdomain before onboarding
“Before we onboard acmecorp.com as a customer, can you check whether portal.acmecorp.com has any TXT DNS records and whether the subdomain actually exists?”
Audit competitor portal infrastructure
“I'm researching competitor infrastructure — can you look up the TXT records on the portal subdomain of salesforce.com and tell me what's there?”
Validate DNS config after setup
“We just configured our portal subdomain — can you verify that portal.mycompany.io now has TXT records in DNS and what the TTL is?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/portal/txt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, targeted TXT record existence check specifically for the 'portal' subdomain of a domain, without needing to enumerate all subdomains. Prefer this over general DNS lookup tools when you want a focused, cheap ($0.01) single-subdomain check routed through Cloudflare's DoH for privacy and reliability.
Side effects
- Domain not found or has no portal subdomain — returns no records or NXDOMAIN
- Invalid domain name format causes lookup failure
- Cloudflare DoH upstream timeout or error
- Missing required domain input parameter
