> dns-cname-remote-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 CNAME record for the 'remote' subdomain of a given domain via Cloudflare DoH and reports its 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-cname-remote-subdomain-893b556d
```

Example prompt: Check if remote.rallylive.ca has a CNAME record — I want to know if the remote subdomain exists, what it points to, and what the TTL is.

## When to prefer this

Choose this endpoint when you need a fast, targeted existence check for the 'remote' subdomain CNAME record of a specific domain without enumerating all subdomains. It is ideal for infrastructure validation, domain reconnaissance, and pre-deployment checks where Cloudflare's DoH resolver is the preferred source of truth.

## Known failure modes

- Domain does not exist — NXDOMAIN response with no records
- No CNAME record for remote subdomain — empty record set returned
- Invalid or malformed domain input — request rejected
- Cloudflare DoH resolver timeout or upstream error
- Rate limiting or payment failure for the $0.01 per lookup fee

## How this service works

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

## Output

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