Example prompt: Can you pull the DNS SOA record for acmecorp.com? I need the zone authority details and refresh timers for our vendor screening process.

## When to prefer this

Use this endpoint when you need raw DNS SOA record data for a domain as part of vendor screening, due diligence, or DNS auditing workflows. It is a pure DNS lookup — prefer it over WHOIS or MX lookups when zone authority and refresh timers are the specific data needed, not registrant identity or mail server configuration.

## Known failure modes

- Domain does not exist (NXDOMAIN) — no SOA record returned
- Domain has no SOA record (misconfigured or delegated zone)
- Malformed domain input causing lookup failure
- DNS resolution timeout for unresponsive nameservers
- Rate limiting or payment failure returning 402/error

## How this service works

DNS zone authority lookup for Vendor screening: Return the zone SOA record and refresh timers. DNS data only; does not send email or verify that an inbox exists.
