## 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-wiki-subdomain-975429fc
```

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

## When to prefer this

Use this endpoint when you need a quick, single-purpose existence and resolution check for the wiki subdomain of a domain, without running a full subdomain enumeration. Prefer it over general DNS tools when you specifically want the A record for wiki.<domain> and want a lightweight, pay-per-use check via Cloudflare DoH.

## Known failure modes

- Domain does not have a wiki subdomain — returns non-existent or NXDOMAIN response
- Invalid or malformed domain name supplied — may return error or empty result
- Cloudflare DoH upstream timeout or failure — lookup may fail or return stale data
- Domain exists but wiki subdomain has no A record (may have CNAME instead) — returns no A records

## How this service works

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

## Output

Returns whether wiki.<domain> exists in DNS, its A record IP address(es), and the TTL of the record, based on a Cloudflare DoH resolution.
