# DNS AAAA Record Lookup for dev Subdomain

> DNS AAAA Record Lookup for dev 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 dev.<domain> subdomain via Cloudflare DNS-over-HTTPS and returns existence status, records, and TTL.

## 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-dev-subdomain-43fe1dbb
```

Example prompt: Can you check whether dev.rallylive.ca has an IPv6 (AAAA) DNS record and tell me what it resolves to and its TTL?

## When to prefer this

Use this endpoint when you specifically need to check the IPv6 (AAAA) DNS record for the 'dev' subdomain of a given domain, particularly for quick existence checks without full subdomain enumeration. Prefer this over generic DNS tools when you want a pay-per-lookup, low-cost, Cloudflare-DoH-backed check focused on the dev host.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code with no records
- dev subdomain has no AAAA record (only A record) — returns empty record set
- Malformed domain input — may return an error or unexpected response
- Cloudflare DoH upstream unavailable — service may return a timeout or error
- Rate limiting or payment failure — request rejected before DNS lookup is performed

## How this service works

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

## Output

Returns whether the dev.<domain> AAAA record exists, the actual IPv6 address records if present, the TTL value, and the DNS response code (e.g. NOERROR, NXDOMAIN).
