Looks up the TXT DNS record for the 'new' subdomain of a given domain via Cloudflare DoH and reports its existence, records, and TTL.

## 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-new-subdomain-b0ce3e24
```

Example prompt: Check whether new.acme.com exists in DNS and show me its TXT records and TTL.

## When to prefer this

Use this endpoint when you need a quick, targeted TXT DNS lookup specifically for the 'new' subdomain of a domain, without enumerating all subdomains. Prefer it over general DNS tools when you want a lightweight, pay-per-use existence check for this common host prefix via a reliable DoH resolver.

## Known failure modes

- Domain does not exist — returns non-existent or NXDOMAIN status
- Subdomain 'new.<domain>' has no TXT records — returns empty result
- Invalid domain format provided — may return error or empty response
- Cloudflare DoH unreachable — service timeout or connectivity error
- Rate limiting or payment failure — 402 payment required

## How this service works

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

## Output

Returns whether the 'new.<domain>' subdomain exists in DNS, its TXT record values (if any), and the TTL of the record, resolved via Cloudflare DoH.
