# is-dns-hosted-by-dnsimple

> is-dns-hosted-by-dnsimple is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Checks whether a domain's DNS is hosted by DNSimple by looking up its NS records and matching them against DNSimple nameserver patterns, returning a yes/no result with matched nameservers.

## 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-dnsimple-ab2d2d7f
```

Example prompt: Can you check if example.com has its DNS hosted by DNSimple — I want to know if the nameservers match DNSimple's patterns and which ones do?

## When to prefer this

Use this endpoint when you need a fast, single-domain check to determine if a domain's DNS is specifically managed by DNSimple. Prefer this over generic NS lookup endpoints when you need the vendor-matching logic built in, saving you from having to manually compare nameserver strings against DNSimple's patterns. Choose the bulk sibling endpoint (is-dns-hosted-by-1and1-bulk style) if you need to check many domains at once.

## Known failure modes

- Domain does not exist or has no NS records — returns no nameservers and hosted=false
- Cloudflare DoH lookup fails or times out — DNS resolution error returned
- Domain provided is malformed or invalid — bad request error
- DNSimple nameserver patterns may not match newly introduced DNSimple nameservers if patterns are not up to date

## How this service works

Is the domain's DNS hosted by dnsimple? Looks up the NS records (Cloudflare DoH) and matches them against dnsimple'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 indicating whether the domain's DNS is hosted by DNSimple, the full list of NS records resolved via Cloudflare DNS-over-HTTPS, and a subset list of those nameservers that matched DNSimple's known nameserver patterns.
