# dns-aaaa-beta-subdomain

> dns-aaaa-beta-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 beta subdomain of a given domain using Cloudflare DNS over HTTPS, reporting 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-beta-subdomain-12ce112d
```

Example prompt: Check if beta.stripe.com has an AAAA record — does it exist, what's the IPv6 address, and what's the TTL?

## When to prefer this

Use this endpoint when you need a fast, cheap existence check for the IPv6 (AAAA) record of the beta subdomain of a specific domain, without needing to enumerate all subdomains. Prefer it over general DNS lookup tools when you specifically care about the beta host and IPv6 reachability. It is not suitable for A (IPv4), MX, TXT, or other record types, or for arbitrary subdomains beyond beta.

## Known failure modes

- Domain does not exist — returns NXDOMAIN with no records
- beta subdomain not configured — NXDOMAIN or empty answer section
- Invalid or malformed domain input — may return error or unexpected result
- Cloudflare DoH upstream temporarily unavailable — request may timeout or fail
- Network/payment failure — x402 payment not processed, no response returned

## How this service works

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

## Output

Returns whether the AAAA record for beta.<domain> exists, along with any IPv6 addresses found, the TTL value, and the DNS response code (e.g. NOERROR or NXDOMAIN).
