## 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-txt-record-lookup-for-wiki-subdomain-4a5bf2d9
```

Example prompt: Can you check whether there's a wiki subdomain set up for example.com by looking up its TXT DNS records and telling me what you find, including the TTL?

## When to prefer this

Use this endpoint when you need a fast, targeted existence and TXT record check specifically for the wiki subdomain of a domain, without performing broad subdomain enumeration. Ideal for domain audits, competitive research, or infrastructure validation where the wiki host is the specific point of interest.

## Known failure modes

- Domain does not exist — returns no records found
- wiki subdomain not configured — returns empty or NXDOMAIN-equivalent response
- Invalid or malformed domain input — may return error
- Cloudflare DoH upstream timeout — temporary lookup failure
- Rate limiting or payment issues — 402 response if payment not provided

## How this service works

TXT record of wiki.<domain>: looks up the wiki host under the domain you give (TXT 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 the wiki.<domain> TXT DNS record exists, the record values (if any), and the TTL. If the subdomain does not exist, the response indicates absence without enumerating other subdomains.
