Example prompt: Can you look up the TXT DNS records for the beta subdomain of rallylive.ca and tell me whether it exists, what records are set, and its TTL?

## When to prefer this

Use this endpoint when you need a fast, single-purpose TXT record check for specifically the beta subdomain of a domain, without enumerating all subdomains. Prefer this over generic DNS tools when you want a lightweight, pay-per-use lookup via Cloudflare DoH for the common 'beta' host pattern.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code with no records
- beta subdomain has no TXT records — returns NOERROR but empty record set
- Malformed domain input — may return an error or empty response
- Cloudflare DoH upstream timeout or outage — request may fail or return an error

## How this service works

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

## Output

Returns whether the beta.<domain> TXT record exists, the actual TXT record values if present, the TTL, and the DNS response code (e.g. NOERROR or NXDOMAIN) as answered by Cloudflare DoH.
