## How to call it through Zero

```sh
zero fetch --capability dns-ns-record-lookup-3f71aed7
```

Example prompt: What are the authoritative nameservers for stripe.com, and which DNS hosting provider are they using?

## When to prefer this

Use this endpoint when you need to quickly determine who hosts DNS for a domain without running local dig/nslookup commands, or when you need programmatic access to NS records with automatic DNS provider identification. Ideal for infrastructure audits, migration verification, and competitive research.

## Known failure modes

- Domain does not exist or has no NS records — returns empty or error response
- Network timeout reaching upstream DNS resolvers
- Invalid or malformed domain name input — likely returns a validation error
- Domain is using obscure/private nameservers not recognized by the provider detection heuristics — provider may be returned as unknown

## How this service works

DNS NS record lookup: the authoritative nameservers for a domain and the detected DNS hosting provider (Cloudflare, Route 53, Google Cloud DNS, Azure, NS1, GoDaddy, Namecheap...). Infrastructure discovery and migration checks. $0.01 per lookup.

## Output

Returns the list of authoritative nameserver hostnames (NS records) for the queried domain and a detected DNS hosting provider label (e.g. Cloudflare, Amazon Route 53, Google Cloud DNS, Azure DNS, NS1, GoDaddy, Namecheap).
