# DNS A Record Lookup for git Subdomain

> DNS A Record Lookup for git 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 of git.<domain> via Cloudflare DNS-over-HTTPS and reports whether the host exists, its IP 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-record-lookup-for-git-subdomain-8b59369f
```

Example prompt: Can you check if gitlab.com has a git subdomain set up — look up the A record for git.gitlab.com and tell me its IP and TTL?

## When to prefer this

Use this endpoint when you need a fast, targeted existence check for the git subdomain of a specific domain without enumerating all subdomains. Ideal for infrastructure reconnaissance, pre-integration checks, or verifying DNS configuration for git hosting. Prefer this over general DNS tools when you specifically care about the git host and want a simple pay-per-lookup model at $0.01/call.

## Known failure modes

- Domain does not have a git subdomain — returns non-existence result
- Invalid or malformed domain input — may return error or empty result
- Cloudflare DoH upstream timeout or outage — lookup fails
- NXDOMAIN for git.<domain> — subdomain simply not configured
- Rate limiting or payment failure — request rejected

## How this service works

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

## Output

Returns whether git.<domain> exists as a DNS A record, the resolved IP address(es), and the TTL of the record. If the subdomain does not exist, indicates non-existence.
