# dns-a-new-subdomain

> dns-a-new-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 A record for the 'new' subdomain of a given domain via Cloudflare DNS over HTTPS and reports whether it exists, its 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-a-new-subdomain-3204f0e3
```

Example prompt: Can you check whether the 'new' subdomain of stripe.com exists — does new.stripe.com resolve, and if so, what IP address does it point to?

## When to prefer this

Use this endpoint when you need a fast, single-purpose check of whether the 'new' subdomain of a specific domain resolves via A record, without needing to enumerate all subdomains. Prefer it over general DNS tools when you specifically want the 'new' host and want a pre-built, pay-per-call microservice backed by Cloudflare DoH for reliability.

## Known failure modes

- Domain does not exist or has no DNS records — returns NXDOMAIN or empty result
- new.<domain> exists in DNS but has no A record (e.g. only CNAME or AAAA) — returns empty A record set
- Network or Cloudflare DoH upstream timeout — returns error response
- Malformed or missing domain input — returns 400-level error
- SERVFAIL from upstream resolver — propagated as error in response

## How this service works

A record of new.<domain>: looks up the new host under the domain you give (A via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like new without enumerating subdomains. $0.01 per lookup.

## Output

Returns whether the A record for new.<domain> exists, the resolved IP address(es), the TTL of the record, and metadata about the DNS response as answered by Cloudflare DoH.
