Example prompt: Can you check if the staging subdomain for rallylive.ca has a CNAME record set up — I need to know if it exists and what it points to?

## When to prefer this

Use this endpoint when you need a fast, single-purpose existence check for the staging.<domain> CNAME record without enumerating all subdomains. Prefer this over full subdomain enumeration tools when you only care about the staging host specifically, and over generic DNS tools when you want a paid, reliable DoH-backed lookup with a simple API.

## Known failure modes

- Domain has no staging subdomain CNAME record — returns NXDOMAIN or empty record set
- Invalid or malformed domain name input causes lookup failure
- Cloudflare DoH service temporarily unavailable — network error
- Domain does not exist at all — NXDOMAIN at apex level
- Staging subdomain exists as A/AAAA but not CNAME — returns no CNAME records

## How this service works

CNAME record of staging.<domain>: looks up the staging 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 staging without enumerating subdomains. $0.01 per lookup.

## Output

Returns whether the CNAME record for staging.<domain> exists, the actual CNAME record value(s), the TTL, and the DNS response code (e.g. NOERROR or NXDOMAIN), as resolved via Cloudflare DoH.
