## How to call it through Zero

```sh
zero fetch --capability is-dns-hosted-by-hetzner-bc7ab1b5
```

Example prompt: Can you check if example.com has its DNS hosted by Hetzner — I need to know if it uses Hetzner nameservers and which ones matched?

## When to prefer this

Choose this endpoint when you specifically need to detect Hetzner as a DNS hosting provider for a domain. It is purpose-built for Hetzner vendor detection using Cloudflare DoH for reliable NS resolution, making it ideal for sales enrichment, migration planning, or infrastructure auditing workflows where Hetzner identification is the goal. Use sibling endpoints for detecting other DNS providers like Cloudflare.

## Known failure modes

- Domain does not exist or has no NS records — returns no match with empty nameserver list
- Cloudflare DoH unavailable — lookup fails with a service error
- Invalid or malformed domain input — returns an error or empty result
- Domain uses private or uncommon nameservers that superficially resemble Hetzner patterns — possible false positive

## How this service works

Is the domain's DNS hosted by hetzner? Looks up the NS records (Cloudflare DoH) and matches them against hetzner'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 indicator of whether the domain's DNS is hosted by Hetzner, the full list of NS records retrieved via Cloudflare DoH, and the subset of nameservers that matched Hetzner's known nameserver patterns.
