Example prompt: Can you look up the nameserver records for stripe.com so I can check what DNS infrastructure they're using as part of our vendor screening process?

## When to prefer this

Use this endpoint when you specifically need DNS nameserver (NS) records for a domain as part of vendor screening, third-party risk assessment, or infrastructure audits. Prefer this over generic DNS tools when you need a lightweight, pay-per-call API integrated into an agentic workflow focused on vendor due diligence. It does not verify email deliverability or perform MX lookups.

## Known failure modes

- Domain does not exist or has no NS records — returns empty or error response
- Malformed domain input (e.g. includes protocol or path) — may return error
- Private or internal domains not resolvable via public DNS — no records returned
- Temporary DNS resolution failure — transient error requiring retry

## How this service works

Nameserver lookup for Vendor screening: Return the domain name-server records. DNS data only; does not send email or verify that an inbox exists.

## Output

Returns the authoritative nameserver (NS) records associated with the queried domain, including the hostnames of the nameservers responsible for that domain's DNS resolution. No email verification or inbox validation is performed — purely DNS data.
