# DNS AAAA Record Lookup for autoconfig Subdomain

> DNS AAAA Record Lookup for autoconfig 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 of the autoconfig subdomain under 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-record-lookup-for-autoconfig-subdomain-580f9221
```

Example prompt: Does autoconfig.example.com have an IPv6 DNS record? Check the AAAA record for that subdomain and tell me if it exists, what address it resolves to, and what the TTL is.

## When to prefer this

Use this endpoint when you need a fast, targeted check of whether the autoconfig subdomain of a specific domain has an IPv6 (AAAA) DNS record, without needing to enumerate all subdomains or query multiple record types. Ideal for email infrastructure checks, IPv6 readiness audits, or monitoring pipelines that need a single specific data point about a well-known subdomain.

## Known failure modes

- Domain does not exist — DNS NXDOMAIN response, no records returned
- autoconfig subdomain not configured — empty or NOERROR with no AAAA records
- Invalid or malformed domain input — API may return error or unexpected result
- Cloudflare DoH unreachable — service returns error or timeout
- Domain has only A (IPv4) records, not AAAA — record absent but domain exists

## How this service works

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

## Output

Returns whether the autoconfig.<domain> AAAA record exists, the IPv6 address(es) in the record, the TTL value, and the DNS response code from Cloudflare's DoH resolver.
