# dns-aaaa-imap-subdomain

> dns-aaaa-imap-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 imap subdomain of a given domain via Cloudflare DoH, returning existence status, 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-imap-subdomain-c999eadd
```

Example prompt: Can you check if imap.example.com has an IPv6 AAAA DNS record, and tell me what the record says and its TTL?

## When to prefer this

Choose this endpoint when you need a fast, targeted IPv6 DNS existence check specifically for the imap subdomain of a domain without performing a broader subdomain enumeration. It is ideal for email infrastructure audits, mail server IPv6 readiness validation, and onboarding checks where you already know the subdomain pattern is 'imap' and want a single cheap lookup ($0.01) via the trusted Cloudflare DoH resolver.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code with no records
- imap subdomain not configured for IPv6 — returns NXDOMAIN or empty AAAA result
- Malformed domain input — may return error or unexpected result
- Cloudflare DoH upstream unavailable — service may timeout or return error
- Rate limiting or payment failure — request rejected at x402 payment layer

## How this service works

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

## Output

Returns whether the AAAA record for imap.<domain> exists, the IPv6 address records found, the TTL of those records, and the DNS response code (e.g. NOERROR or NXDOMAIN), as resolved by Cloudflare DNS over HTTPS.
