# dns-aaaa-support-subdomain

> dns-aaaa-support-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 2026-10-20).

Looks up the AAAA (IPv6) DNS record for the support subdomain of a given domain via Cloudflare DoH, 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-support-subdomain-39304b24
```

Example prompt: Check if support.stripe.com has an IPv6 DNS record — I need to know if the support subdomain exists and what its AAAA record and TTL look like.

## When to prefer this

Use this endpoint when you specifically need to check IPv6 (AAAA) DNS records for the support subdomain of a domain, as opposed to the A record (IPv4). Prefer this over generic DNS resolvers when you want a quick, pay-per-use existence check without running your own DNS infrastructure. Ideal for infrastructure audits, IPv6 readiness checks, and verifying support portal DNS configuration.

## Known failure modes

- Domain does not have a support subdomain AAAA record — returns not found or empty record set
- Invalid or malformed domain name input — may return an error or empty result
- Cloudflare DoH upstream timeout or outage — request may fail or return no data
- Domain itself does not exist (NXDOMAIN) — returns non-existence
- Rate limiting or payment failure — request rejected with 402 or 429 error

## How this service works

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

## Output

Returns whether the AAAA record for support.<domain> exists, the IPv6 address(es) in the record, and the TTL value. If the record does not exist, reports its absence.
