## 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-aaaa-record-lookup-for-ns1-subdomain-via-cloudflare-doh-86f67beb
```

Example prompt: Can you check if ns1.example.com has an IPv6 AAAA DNS record — I want to know if the ns1 host exists and what its IPv6 address and TTL are?

## When to prefer this

Use this endpoint when you need a quick, targeted IPv6 DNS check specifically for the ns1 host under a domain, without needing to enumerate all subdomains. Prefer it over generic DNS tools when you want a pre-scoped, pay-per-lookup check for this common nameserver subdomain pattern via Cloudflare's trusted DoH resolver.

## Known failure modes

- Domain has no ns1 subdomain — returns NXDOMAIN or empty record set
- Domain does not exist — returns resolution failure
- ns1 subdomain exists but only has A (IPv4) record, not AAAA — returns empty result
- Network or DoH resolver timeout — returns error
- Malformed domain input — returns validation error

## How this service works

AAAA record of ns1.<domain>: looks up the ns1 host under the domain you give (AAAA via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like ns1 without enumerating subdomains. $0.01 per lookup.

## Output

Returns whether the ns1 subdomain of the given domain has an AAAA (IPv6) DNS record, the actual record value(s) if present, the TTL, and the DNS response code — sourced from Cloudflare DNS over HTTPS.
