Example prompt: Can you check if wiki.acmecorp.com exists by looking up its CNAME DNS record?

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.01) existence check specifically for the wiki subdomain of a domain without running a full subdomain enumeration. Prefer this over general-purpose DNS tools when you specifically want the CNAME record type for the wiki host and want results routed through Cloudflare DoH for reliability and speed.

## Known failure modes

- Domain does not exist — returns no records found
- wiki subdomain has no CNAME record (may have A record instead) — returns empty CNAME result
- Invalid or malformed domain input — may return error or empty response
- Cloudflare DoH upstream timeout — may result in a lookup failure
- Network or resolver error from Cloudflare DoH service

## How this service works

CNAME record of wiki.<domain>: looks up the wiki host under the domain you give (CNAME via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like wiki without enumerating subdomains. $0.01 per lookup.

## Output

Returns whether the wiki.<domain> CNAME record exists, the resolved DNS record value(s), and the TTL. If the subdomain does not exist, it reports its absence without enumerating other subdomains.
