## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nameserver-lookup-for-security-review-6b09ed7d -d '<json body>'
```

Example prompt: Look up the nameserver records for suspicious-site.com so I can check which DNS provider is managing it as part of a security review.

## When to prefer this

Choose this endpoint when you specifically need the authoritative nameserver (NS) records for a domain as part of a security review, threat investigation, or DNS infrastructure audit. It is distinct from MX, A, or WHOIS lookups — use it when you want to know which DNS provider or registrar is managing a domain's name resolution, not email routing or IP addresses.

## Known failure modes

- Domain does not exist or has no NS records — returns empty or NXDOMAIN result
- Invalid domain format provided — may return validation error
- DNS resolution timeout for slow or unreachable nameservers
- Domain is a private/internal name not resolvable via public DNS

## How this service works

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

## Output

Returns the DNS nameserver (NS) records for the queried domain — specifically the authoritative nameserver hostnames delegated to manage the domain's DNS. No email verification or inbox checking is performed; this is raw DNS data only.
