# DNS AAAA Record Lookup for SSO Subdomain

> DNS AAAA Record Lookup for SSO 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 IPv6 AAAA DNS record for the sso.<domain> subdomain 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-record-lookup-for-sso-subdomain-8618ccc4
```

Example prompt: Check if sso.example.com has an IPv6 AAAA DNS record and tell me the address and TTL if it exists.

## When to prefer this

Use this endpoint when you specifically need to check IPv6 (AAAA) DNS records for the sso subdomain of a given domain, rather than doing a full subdomain enumeration. It is ideal for quick existence checks of the SSO host with IPv6 support, security audits, or pre-integration verification. Prefer this over general DNS tools when you want a focused, single-host IPv6 check with a known per-call cost.

## Known failure modes

- Domain does not have an sso subdomain — returns no records found
- Invalid or malformed domain input — may return error or empty result
- Network or Cloudflare DoH unavailability — lookup may time out
- Domain has sso subdomain but only A (IPv4) records, not AAAA — returns no AAAA records

## How this service works

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

## Output

Returns whether the sso.<domain> subdomain exists, its AAAA (IPv6) DNS records, and the TTL of those records as resolved via Cloudflare DoH.
