## How to call it through Zero

```sh
zero fetch --capability dns-ns-via-adguard-a3a67b21
```

Example prompt: What NS records does AdGuard DNS return for example.com, and did it validate DNSSEC?

## When to prefer this

Choose this endpoint when you specifically want to see how AdGuard DNS resolves NS records — particularly to detect DNS filtering, compare AdGuard's answer against other resolvers for propagation lag or split-horizon differences, or verify DNSSEC validation behavior at the AdGuard resolver. Prefer this over generic DNS lookup tools when AdGuard's privacy-focused or ad-blocking DNS policies may affect the answer.

## Known failure modes

- Domain not found returns NXDOMAIN response code
- Resolver failure returns SERVFAIL response code
- Missing or invalid domain parameter results in an error response
- Network timeout from AdGuard DNS upstream may cause delayed or failed response
- DNSSEC validation failure may be indicated in the response rather than causing an endpoint error

## How this service works

NS records for a domain as answered by AdGuard DNS (DNS over HTTPS): the records, TTL, response code (NOERROR/NXDOMAIN/SERVFAIL), whether the resolver validated DNSSEC, and the resolver's answer time. Compare resolvers to spot propagation lag, filtering or split-horizon answers. $0.01 per lookup.

## Output

Returns the NS records (nameserver hostnames) for the queried domain, the TTL of those records, the DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a flag indicating whether AdGuard DNS validated DNSSEC for the response, and the resolver's answer latency in milliseconds.
