# dns-a-news-subdomain

> dns-a-news-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 (IPv4) DNS record for the 'news' subdomain of a given domain via Cloudflare DoH and returns its existence, IP 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-a-news-subdomain-85f91a97
```

Example prompt: Does techcrunch.com have a 'news' subdomain? Look up the A record for news.techcrunch.com and tell me the IP address and TTL if it exists.

## When to prefer this

Use this endpoint when you need a quick, low-cost existence check specifically for the 'news' subdomain of a domain without enumerating all subdomains. Prefer it over full subdomain enumeration tools when you only care about the standard 'news' host. Ideal for bulk pipeline checks where you want to verify presence of a news subdomain before further action.

## Known failure modes

- Domain does not exist — returns NXDOMAIN or no records found
- news subdomain not configured — returns empty record set
- Invalid domain format provided — may return error or empty result
- Cloudflare DoH service timeout or unavailability
- Domain has AAAA records only (IPv6) — A record lookup returns nothing

## How this service works

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

## Output

Returns whether the news.<domain> A record exists, the resolved IPv4 address(es), and the TTL value for the record as reported by Cloudflare's DNS over HTTPS service.
