How this service works
TXT record of _domainkey.<domain>: looks up the _domainkey 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 _domainkey without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the _domainkey.<domain> host exists in DNS, the raw TXT record values if present, and the TTL of the record as resolved via Cloudflare DNS over HTTPS.
Example use cases
Email infrastructure audit for a domain
“I'm auditing the email setup for acmecorp.com — can you check if there's a _domainkey TXT record and tell me what it contains and its TTL?”
Pre-deployment DKIM infrastructure check
“Before we go live, can you confirm that _domainkey.mycompany.io exists as a TXT record in DNS and what value it has?”
Competitor email signing setup investigation
“I want to know if rivalfirm.com has a _domainkey TXT record set up — can you look it up and tell me whether it exists and what the record says?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/domainkey/txt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, single-shot existence and content check for the _domainkey TXT DNS record of a specific domain, without needing to enumerate all subdomains. Prefer this over general DNS tools when you specifically want _domainkey lookup via Cloudflare DoH with a pay-per-use model and no API key setup required.
Side effects
- Domain does not exist — returns non-existence or NXDOMAIN result
- No _domainkey TXT record configured — reports record not found
- Malformed domain input — may return an error or empty result
- Cloudflare DoH upstream timeout — service may return an error
- Invalid or unparseable domain string — lookup fails
