## 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 is-dns-hosted-by-cloudns-e1623cb4
```

Example prompt: Check if the domain acmecorp.com has its DNS hosted by ClouDNS — I need to know yes or no, which nameservers it has, and which ones match the ClouDNS pattern.

## When to prefer this

Use this endpoint when you need to specifically detect whether a domain is using ClouDNS as its DNS provider. It is purpose-built for ClouDNS vendor detection (vs generic NS lookup endpoints) and returns structured match results indicating exactly which nameservers matched ClouDNS patterns. Prefer this over general DNS lookup tools when doing vendor-targeted sales prospecting, DNS migration verification, or security-focused infrastructure fingerprinting against ClouDNS specifically.

## Known failure modes

- Domain does not exist — NS lookup returns empty or NXDOMAIN
- Cloudflare DoH unavailable — DNS resolution fails
- Domain has no NS records — inconclusive result
- Ambiguous nameserver patterns — partial matches may be misclassified
- Network timeout from Cloudflare DoH upstream

## How this service works

Is the domain's DNS hosted by cloudns? Looks up the NS records (Cloudflare DoH) and matches them against cloudns's nameserver patterns, returning yes/no, the nameservers and which ones matched. Vendor detection for sales, migration and security work. $0.01 per lookup.

## Output

Returns a boolean yes/no indicating whether the domain's DNS is hosted by ClouDNS, the full list of NS records found via Cloudflare DoH, and a subset list of the nameservers that matched ClouDNS nameserver patterns.
