## When to prefer this

Choose this endpoint when you need a fast, single-shot existence check for the jenkins subdomain's TXT record of a specific domain without running a full subdomain enumeration. Ideal for infrastructure audits, CI/CD presence detection, and security reconnaissance where Cloudflare DoH resolution accuracy is preferred over recursive DNS.

## Known failure modes

- Domain does not exist — NXDOMAIN response returned
- No TXT record exists for jenkins subdomain — empty records with existence=false
- Invalid domain format provided as input
- Cloudflare DoH upstream timeout or unavailability
- Rate limiting or payment failure for $0.01 USDC per call

## How this service works

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

## Output

Returns whether the TXT record for jenkins.<domain> exists, the actual TXT record string(s) if present, and the TTL (time-to-live) value for the record as resolved via Cloudflare DoH.
