## 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-community-domain-bd86a3f7
```

Example prompt: Check if the community subdomain exists for discourse.org — look up its CNAME record and tell me what it resolves to and the TTL.

## When to prefer this

Use this endpoint when you need a quick, targeted existence check for the 'community' subdomain specifically on a given domain, without performing broad subdomain enumeration. Ideal for verifying community forum hosting setup (e.g. Discourse, Khoros) or auditing whether a domain has a community presence configured.

## Known failure modes

- Domain does not have a community subdomain — returns no records or NXDOMAIN
- Invalid or malformed domain input returns an error
- Cloudflare DoH temporary unavailability causes lookup failure
- Rate limiting or quota exceeded on the $0.01/call pricing model

## How this service works

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

## Output

Returns whether the community.<domain> CNAME record exists, the resolved CNAME target(s), and the DNS TTL value for the record, queried via Cloudflare DoH.
