## How to call it through Zero

```sh
zero fetch --capability dns-a-community-subdomain-aabfe666
```

Example prompt: Can you check whether the community subdomain exists for rallylive.ca — look up its A record and tell me the IP address and TTL if it resolves?

## When to prefer this

Use this endpoint when you specifically need to check the A record of the community.<domain> subdomain for a given domain — ideal for quick existence checks without enumerating subdomains. Prefer this over general DNS tools when you want a targeted, low-cost single-host lookup routed through Cloudflare for reliability and consistency.

## Known failure modes

- Domain does not have a community subdomain configured — returns NXDOMAIN response
- Invalid or malformed domain input — may return error or empty result
- Cloudflare DoH upstream unavailable — request may time out
- Domain exists but community host has no A record (may have CNAME or other record types instead)

## How this service works

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

## Output

Returns whether the community.<domain> A record exists, the resolved IP address(es), the TTL value, and the DNS response code (e.g. NOERROR or NXDOMAIN) as answered by Cloudflare DoH.
