> is-dns-hosted-by-linode 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 Linode by looking up its NS records via Cloudflare DoH and matching them against Linode's nameserver patterns, returning a yes/no answer 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-linode-dcfa5f95
```

Example prompt: Can you check whether example.com has its DNS hosted by Linode? I want to know if they use Linode nameservers and which ones matched.

## When to prefer this

Choose this endpoint when you specifically need to detect whether a domain's DNS is hosted by Linode, particularly for sales intelligence, vendor auditing, migration planning, or security investigations. It is purpose-built for Linode vendor detection via NS record matching using Cloudflare DoH, making it more reliable and specific than generic NS lookup tools for this use case.

## Known failure modes

- Domain does not exist or has no NS records — returns no match with empty nameserver list
- Cloudflare DoH is temporarily unavailable — lookup fails with a connectivity error
- Invalid or malformed domain name input — returns an error or no results
- Domain uses a Linode-adjacent but unrecognized nameserver pattern — may return false negative

## How this service works

Is the domain's DNS hosted by linode? Looks up the NS records (Cloudflare DoH) and matches them against linode'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 yes/no boolean indicating whether the domain's DNS is hosted by Linode, the full list of NS records retrieved via Cloudflare DoH, and a subset of nameservers that matched Linode's known nameserver patterns.
