# dns-aaaa-id-subdomain

> dns-aaaa-id-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 'id' subdomain of a given domain via Cloudflare DoH and reports 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-id-subdomain-2f5a7522
```

Example prompt: Can you check whether id.acme.com has an AAAA record — I want to know if it resolves over IPv6 and what the TTL is?

## When to prefer this

Use this endpoint when you need a fast, targeted IPv6 DNS existence check specifically for the 'id' subdomain of a domain, without enumerating all subdomains. Ideal for automated infrastructure checks, pre-launch validation, or domain intelligence gathering where the id host is a known common pattern.

## Known failure modes

- Domain does not exist — returns no record found
- id subdomain not configured — AAAA record absent, returns empty result
- Cloudflare DoH temporary failure — upstream resolver error
- Invalid or malformed domain input — request may fail or return error
- Network timeout — DoH query takes too long

## How this service works

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

## Output

Returns whether the AAAA record for id.<domain> exists, the IPv6 address(es) found, and the TTL value; or reports that no record was found if the subdomain does not exist.
