# dns-aaaa-test-subdomain

> dns-aaaa-test-subdomain is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Looks up the AAAA (IPv6) DNS record for the 'test' subdomain of a given domain via Cloudflare DoH and reports its existence, records, and TTL.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-test-subdomain-aba99eed
```

Example prompt: Can you check whether test.example.com has an IPv6 address configured in DNS — specifically the AAAA record for that test subdomain?

## When to prefer this

Use this endpoint when you need a quick, single-resolver check on whether the 'test' subdomain of a specific domain has an IPv6 (AAAA) record configured, without needing to enumerate all subdomains. Prefer it over full DNS enumeration tools when you only care about this specific common hostname. Best suited for infrastructure validation, security audits, and DNS propagation checks for IPv6.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code with no records
- test subdomain has no AAAA record configured — returns NOERROR but empty answer section
- Invalid domain format provided — may return an error or empty response
- Cloudflare DoH upstream temporarily unavailable — request may time out or return a server error

## How this service works

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

## Output

Returns whether the AAAA record for test.<domain> exists, the IPv6 address records if present, the TTL value, and the DNS response code (e.g. NOERROR, NXDOMAIN) as resolved by Cloudflare DoH.
