## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability dns-cname-intranet-subdomain-lookup-c8cb007b
```

Example prompt: Can you check if there's a CNAME record for the intranet subdomain of acme.com — I want to know if it exists, what it points to, and what the TTL is?

## When to prefer this

Choose this endpoint when you specifically need to check whether the intranet subdomain of a given domain has a CNAME DNS record, using Cloudflare DoH as the resolver. It is faster and more targeted than full subdomain enumeration tools and is ideal for quick existence checks on this specific common host name. Prefer this over generic CNAME lookups when you want Cloudflare's resolution perspective specifically for the intranet host pattern.

## Known failure modes

- Domain does not exist — NXDOMAIN response with no records
- No CNAME record at intranet.<domain> — empty record set returned
- Domain input missing or malformed — request fails validation
- Cloudflare DoH upstream timeout or unavailability — service error
- Rate limiting or payment failure for $0.01 USDC per call

## How this service works

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

## Output

Returns whether a CNAME record exists for the intranet.<domain> subdomain, the CNAME target record(s), the TTL value, and the DNS response code — all resolved via Cloudflare DNS over HTTPS.
