## 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-mobile-domain-3fe6240a
```

Example prompt: Can you check whether mobile.acmecorp.com has any IPv6 (AAAA) DNS records, and if so what addresses and TTL it returns?

## When to prefer this

Use this endpoint when you specifically need to check whether the 'mobile' subdomain of a domain has IPv6 (AAAA) DNS records, without enumerating all subdomains. Prefer this over a generic DNS resolver when you want a quick, paid, reliable existence check via Cloudflare DoH for a well-known subdomain pattern. It is especially useful for infrastructure audits, IPv6 readiness checks, and pre-launch verification of mobile subdomains.

## Known failure modes

- Domain does not exist (NXDOMAIN) — returns no records and a non-existent response code
- mobile subdomain has no AAAA records (may have A records only) — returns empty record set
- Invalid or malformed domain input — may return an error or empty response
- Cloudflare DoH upstream timeout or outage — request may fail or return an error
- Rate limiting or payment failure — request rejected before DNS query is made

## How this service works

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

## Output

Returns whether the mobile.<domain> host exists in DNS, its AAAA (IPv6) records (addresses), the TTL value, and the DNS response code — all as answered by Cloudflare DNS over HTTPS.
