> is-dns-hosted-by-azure-dns is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Checks whether a domain's DNS is hosted by Azure DNS by looking up its NS records and matching them against Azure DNS nameserver patterns, returning a yes/no verdict plus the 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-azure-dns-6fe8a642
```

Example prompt: Can you check if contoso.com has its DNS hosted by Azure DNS — I need to know if they're an Azure customer for my sales research?

## When to prefer this

Use this endpoint when you need a fast, single-domain check to determine if a specific domain's DNS is managed by Azure DNS for sales prospecting, infrastructure auditing, or security reconnaissance. Prefer it over the bulk Tucows equivalent when only one domain is being checked. Best suited for real-time agent workflows where vendor detection is needed on demand and cost per lookup is acceptable at $0.01 USDC.

## Known failure modes

- Domain does not exist or has no NS records — returns empty nameserver list with 'no' verdict
- DNS lookup timeout via Cloudflare DoH — may return an error or incomplete result
- Domain input is malformed or missing — returns a 400-style error
- Azure DNS nameserver pattern list may not cover all Azure DNS variants — could produce false negatives for unusual Azure zones

## How this service works

Is the domain's DNS hosted by azure dns? Looks up the NS records (Cloudflare DoH) and matches them against azure-dns'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 structured response indicating whether the domain's DNS is hosted by Azure DNS (yes/no), the full list of NS records discovered via Cloudflare DoH, and which specific nameservers matched Azure DNS patterns.
