Example prompt: Before I interact with this merchant's site, can you do a live DNS check on checkout.acmeshop.com and tell me if it resolves and what IP addresses it points to?

## When to prefer this

Choose this endpoint when you need a real-time, direct DNS protocol resolution check with no reliance on cached, scraped, or third-party WHOIS/registry data. It is ideal for agent safety checks before interacting with unknown websites or merchants, for confirming newly configured domains are live, or for any workflow requiring a fresh DNS answer rather than a stale dataset lookup.

## Known failure modes

- Domain does not exist or has no DNS records — returns non-resolving status
- Malformed domain name input — may return validation error
- DNS timeout or temporary resolution failure — may return error or non-resolving result
- Network connectivity issue to DNS servers at query time

## How this service works

Part of the Domain Web Trust family: live DNS resolution check for a domain, useful for confirming a domain has valid DNS before an agent interacts with a website or merchant. Reports whether it resolves and to which IPv4/IPv6 addresses. Queries the public DNS protocol directly at request time -- no third-party dataset, no cached or scraped WHOIS/registry data, so there is no resale-terms question.

## Output

Returns whether the queried domain successfully resolves in live DNS, along with the IPv4 and/or IPv6 addresses it resolves to at request time — sourced directly from the public DNS protocol with no caching or third-party dataset.
