# dns-a-gitlab-subdomain

> dns-a-gitlab-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 DNS A record for the gitlab.<domain> subdomain via Cloudflare DoH and reports its existence, IP addresses, 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-gitlab-subdomain-5f59f1db
```

Example prompt: Can you check if example.com has a gitlab subdomain set up — look up the A record for gitlab.example.com and tell me if it exists, what IP it points to, and the TTL?

## When to prefer this

Use this endpoint when you specifically need to check whether a domain has a GitLab host configured as an A record (IPv4). Prefer this over a generic DNS tool when you want a quick, cheap ($0.01) existence check for the gitlab subdomain specifically without enumerating all subdomains. Use the sibling AAAA endpoint if you also need IPv6 resolution.

## Known failure modes

- Domain does not exist — returns no records found
- Subdomain has no A record (may have AAAA or CNAME instead) — returns empty result
- Invalid or malformed domain input — may return error or empty result
- Cloudflare DoH upstream timeout — may return error
- Domain exists but gitlab subdomain is not configured — returns NXDOMAIN or empty

## How this service works

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

## Output

Returns whether the gitlab.<domain> A record exists, the resolved IPv4 address(es), the TTL in seconds, and a status indicating if the host was found or does not exist.
