# DNS AAAA Record Lookup for sandbox Subdomain

> DNS AAAA Record Lookup for sandbox 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 2026-10-22).

Looks up the AAAA (IPv6) DNS record for the sandbox subdomain of a given domain via Cloudflare DoH and reports existence, records, and TTL.

## 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-sandbox-subdomain-821a78d7
```

Example prompt: Can you check if sandbox.acmecorp.com has an IPv6 DNS record — I want to know if it exists, what its AAAA records are, and what the TTL is?

## When to prefer this

Use this endpoint when you specifically need to check the AAAA (IPv6) DNS record for the 'sandbox' subdomain of a domain, without enumerating other subdomains. Prefer it over general DNS tools when you want a quick, targeted IPv6 existence check for a sandbox host with a per-lookup cost model via x402 micropayments.

## Known failure modes

- Domain not provided or malformed — returns error or empty result
- sandbox subdomain does not exist — returns non-existence response
- Cloudflare DoH upstream timeout or failure — may return error
- Invalid or non-existent TLD — DNS resolution fails
- Rate limiting or payment failure via x402 — request rejected

## How this service works

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

## Output

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