How this service works
TXT record of autoconfig.<domain>: looks up the autoconfig 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 autoconfig without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the TXT record at autoconfig.<domain> exists, the record values (string data), the TTL in seconds, and the DNS response code (e.g. NOERROR or NXDOMAIN), as answered by Cloudflare DoH.
Example use cases
Email client autoconfig DNS audit
“Does gmail.com have a TXT record set up at autoconfig.gmail.com? Show me the record and its TTL.”
Verify self-hosted mail server setup
“I just set up my mail server on mydomain.org — can you check if the autoconfig TXT record is live yet at autoconfig.mydomain.org?”
Domain due diligence before acquisition
“Before we acquire targetcompany.com, can you check whether autoconfig.targetcompany.com has any TXT records configured and what they say?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/autoconfig/txt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need the TXT record for the autoconfig subdomain of a given domain, without enumerating subdomains. It is faster and cheaper than a full subdomain scan and is ideal for verifying email autoconfiguration DNS entries (RFC 6186 / Mozilla-style autoconfig). Prefer it over generic DNS TXT lookup tools when the target is always the autoconfig.<domain> host pattern.
Side effects
- Domain does not exist — returns NXDOMAIN response code with no records
- autoconfig subdomain has no TXT record — record set is empty but domain resolves
- Network or upstream Cloudflare DoH failure — service may return error or timeout
- Malformed domain input — may return error or unexpected result
- Domain with DNSSEC issues — may cause resolution failure
