## 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-ci-subdomain-928105d2
```

Example prompt: Can you check whether ci.github.com has an IPv6 AAAA DNS record and tell me what the record value and TTL are?

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.01) point-in-time check of whether a specific domain has a ci subdomain with an IPv6 AAAA record, without needing to enumerate all subdomains. Ideal for infrastructure audits, pre-deployment checks, or IPv6 readiness validation focused on the CI host specifically.

## Known failure modes

- Domain does not exist — returns no records found
- ci subdomain not configured — returns empty record set with existence false
- Invalid or malformed domain input — may return error or empty result
- Cloudflare DoH upstream timeout or unavailability — returns lookup failure
- Network or payment authorization failure — request not processed

## How this service works

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

## Output

Returns whether the ci.<domain> subdomain has an AAAA (IPv6) DNS record, the actual record value(s) (IPv6 addresses), the TTL in seconds, and an existence flag — all resolved via Cloudflare DNS over HTTPS.
