## 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`):

```

Example prompt: Can you check whether ns2.example.com has a CNAME record and what it resolves to?

## When to prefer this

Use this endpoint when you specifically need to check the CNAME record for the ns2 subdomain of a domain — for example during DNS audits, infrastructure discovery, or pre-migration checks — without needing to enumerate all subdomains. Prefer this over general DNS tools when you want a lightweight, targeted ns2 CNAME existence check at low cost ($0.01 per lookup).

## Known failure modes

- Domain does not exist or has no ns2 host — returns no records found
- Invalid or malformed domain input — may return an error or empty result
- Cloudflare DoH unreachable — upstream resolution failure
- ns2 host exists but has an A/AAAA record rather than a CNAME — result will reflect no CNAME present

## How this service works

CNAME record of ns2.<domain>: looks up the ns2 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 ns2 without enumerating subdomains. $0.01 per lookup.

## Output

Returns whether the ns2.<domain> host exists, its CNAME record value(s), and the TTL of the record as resolved via Cloudflare DNS over HTTPS.
