## 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-new-subdomain-7be41229
```

Example prompt: Can you check if there's a CNAME record configured for the 'new' subdomain of rallylive.ca — I want to know if new.rallylive.ca exists and what it points to?

## When to prefer this

Use this endpoint when you specifically need to check whether the 'new' subdomain of a given domain has a CNAME record, without enumerating all subdomains. Prefer this over full DNS enumeration tools when you just need a targeted existence check for this common host label via Cloudflare's reliable DoH resolver. Choose sibling endpoints for different record types (A, AAAA, TXT) or different subdomains.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code with no records
- new.<domain> subdomain has no CNAME record — exists flag is false
- Malformed domain input — may return an error or empty response
- Cloudflare DoH service unavailable — request may time out or fail with a network error
- Rate limiting — excessive lookups may be throttled

## How this service works

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

## Output

Returns whether the CNAME record for new.<domain> exists, the record value(s) (the canonical hostname it points to), the TTL in seconds, and the DNS response code (e.g. NOERROR or NXDOMAIN).
