How this service works
TXT record of autodiscover.<domain>: looks up the autodiscover 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 autodiscover without enumerating subdomains. $0.01 per lookup.
Output
Returns whether the autodiscover.<domain> TXT record exists, the actual TXT record content (if present), and the TTL value. Response includes the DNS response code (e.g. NOERROR, NXDOMAIN) indicating existence or absence of the subdomain.
Example use cases
Email server autodiscover verification
“Check if autodiscover.acmecorp.com has a TXT record set up — I need to confirm the autodiscover subdomain is properly configured before we migrate our Exchange server.”
Domain intelligence pre-check
“Does the domain outlook.com have an autodiscover TXT DNS record? I want to see what it returns and how long the TTL is.”
Troubleshooting email client discovery
“Can you look up the TXT records for the autodiscover subdomain of fabrikam.com? We're having issues with Outlook not finding the mail server automatically and I want to check if the DNS is there.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/autodiscover/txt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, targeted check for the existence and content of the autodiscover TXT DNS record specifically — without enumerating all subdomains. Ideal for email infrastructure validation, Exchange/Office 365 autodiscover configuration checks, and domain reconnaissance tasks where you already know you want the autodiscover host. Prefer over general DNS enumeration tools when you only need this specific well-known hostname.
Side effects
- NXDOMAIN response if autodiscover.<domain> does not exist as a DNS entry
- Empty records array if subdomain exists but has no TXT records
- Network timeout if Cloudflare DoH is temporarily unreachable
- Invalid domain input causing malformed query
- Payment failure if USDC balance insufficient for $0.01 per-call fee
