## 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-docs-subdomain-6c8b205a
```

Example prompt: Can you check whether docs.acmecorp.com has any DNS TXT records and tell me the TTL if it does?

## When to prefer this

Use this endpoint when you need a quick, targeted check on whether the docs subdomain of a given domain has TXT records, without doing broad subdomain enumeration. Ideal for DNS auditing, pre-deployment checks, or verifying documentation host configuration. Prefer over general DNS tools when you specifically need the docs host TXT records via Cloudflare DoH.

## Known failure modes

- Domain not found or no TXT records exist — returns empty or negative existence result
- Invalid domain format — may return an error or empty result
- Cloudflare DoH timeout or upstream DNS failure — service may return an error
- Domain has no docs subdomain configured — reports non-existence cleanly

## How this service works

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

## Output

Returns whether the docs.<domain> subdomain exists in DNS, its TXT records (if any), and the TTL value. Response is sourced from Cloudflare DNS-over-HTTPS.
