## 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-lookup-for-git-subdomain-via-cloudflare-doh-32d9ccc1
```

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

## When to prefer this

Use this endpoint when you specifically need to check the CNAME record for a git subdomain of a given domain — ideal for quickly verifying if a domain has a git hosting service (like GitHub Pages or Gitea) configured without doing broad subdomain enumeration. Prefer this over general CNAME lookup endpoints when your target is specifically the git.<domain> host.

## Known failure modes

- Domain has no git subdomain configured — returns no records found with NXDOMAIN or empty answer
- Invalid or malformed domain name input — may return an error or empty response
- Cloudflare DoH service temporarily unavailable — request may time out
- Domain exists but git subdomain has an A/AAAA record instead of CNAME — returns no CNAME records
- Rate limiting or payment failure — endpoint returns 402 Payment Required

## How this service works

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

## Output

Returns whether the CNAME record for git.<domain> exists, the actual CNAME record value(s), the TTL, and the DNS response code — all resolved via Cloudflare DNS over HTTPS.
