# dns-cname-status-subdomain

> dns-cname-status-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 CNAME record for the status.<domain> subdomain via Cloudflare DoH and reports whether it exists, its 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-cname-status-subdomain-d4de2468
```

Example prompt: Can you check if status.rallylive.ca has a CNAME record set up — I want to know if it exists and what it points to?

## When to prefer this

Use this endpoint when you need a fast, targeted check of whether a specific domain has a status subdomain CNAME configured, without performing broad subdomain enumeration. It is ideal for verifying status page infrastructure, checking customer DNS setup completion, or doing lightweight DNS reconnaissance on a known host pattern.

## Known failure modes

- No CNAME record found — status subdomain does not exist for that domain
- Invalid or malformed domain input returns an error
- Cloudflare DoH upstream timeout or resolver error
- Domain does not exist at all, resulting in NXDOMAIN

## How this service works

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

## Output

Returns whether the status.<domain> CNAME record exists, the resolved CNAME target(s), and the TTL value as reported by Cloudflare's DNS over HTTPS resolver.
