How this service works
A record of autoconfig.<domain>: looks up the autoconfig host under the domain you give (A 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 autoconfig.<domain> A record exists, the resolved IP address(es), the TTL in seconds, and the DNS response code as returned by Cloudflare DoH.
Example use cases
Email client autoconfiguration check
“Does sendgrid.net have an autoconfig host set up? Look up the A record for autoconfig.sendgrid.net and tell me if it exists and what it resolves to.”
Verifying mail server deployment
“We just deployed autoconfig.mycompany.com — can you confirm the A record is live and resolving, and what TTL is set?”
Auditing domain DNS infrastructure
“I'm auditing DNS for protonmail.com — check if autoconfig.protonmail.com has an A record and report any IPs and the TTL.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/host/autoconfig/a?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, targeted check of whether the autoconfig subdomain (used by email clients for autoconfiguration) exists under a specific domain, without enumerating all subdomains. Prefer this over general DNS tools when you specifically need the A record for autoconfig.<domain> resolved via Cloudflare DoH with a simple existence/IP/TTL result.
Side effects
- Domain does not have an autoconfig subdomain — returns non-existent/NXDOMAIN response
- Invalid or malformed domain name input causes lookup failure
- Cloudflare DoH upstream timeout or error
- Domain exists but autoconfig subdomain has no A record (may have CNAME or other record types instead)
- Network connectivity issues to the dns.intel.rallylive.ca service
- Payment failure for the $0.01 USDC per-call fee
