## 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 dns-ns-record-lookup-via-cloudflare-1-1-1-1-doh-5d94ffd5
```

Example prompt: What are the NS records for example.com according to Cloudflare's 1.1.1.1 resolver — include the TTL, DNSSEC validation status, and how long the resolver took to answer?

## When to prefer this

Use this endpoint when you specifically need NS record results as seen by Cloudflare 1.1.1.1, for example to check nameserver propagation to Cloudflare's global resolver network, compare answers between resolvers to detect filtering or split-horizon configurations, or verify DNSSEC validation status of nameserver delegation. Choose this over generic DNS tools when Cloudflare's perspective specifically matters.

## Known failure modes

- Domain does not exist — returns NXDOMAIN response code with no records
- Domain has no NS records — returns NOERROR with empty answer section
- DNS resolution fails at Cloudflare — returns SERVFAIL response code
- DNSSEC validation failure — DNSSEC flag false despite signed zone
- Network timeout reaching Cloudflare DoH endpoint — request error
- Invalid or malformed domain name input — request rejected

## How this service works

NS records for a domain as answered by Cloudflare 1.1.1.1 (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 as resolved by Cloudflare 1.1.1.1 via DNS over HTTPS, along with the TTL of the records, the DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether Cloudflare validated DNSSEC for the response, and the resolver's answer latency in milliseconds.
