# is-dns-hosted-by-hetzner-bulk

> is-dns-hosted-by-hetzner-bulk is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-20).

Checks whether each domain in a list of up to 20 is using Hetzner's DNS hosting, returning results in input order with per-item error fields and a failure count.

## 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-hetzner-bulk-c120ad72
```

Example prompt: Can you check this list of domains — example.com, mysite.de, coolproject.io — and tell me which ones have their DNS hosted by Hetzner?

## When to prefer this

Use this endpoint when you have a list of 2–20 domains and need to check Hetzner DNS hosting for all of them efficiently in a single call, rather than making separate single-domain requests. It's ideal for bulk auditing, infrastructure screening, or enrichment pipelines where concurrent lookups and ordered, per-item error reporting matter.

## Known failure modes

- Invalid or malformed domain names return a per-item error rather than failing the whole batch
- Domains with no resolvable NS records produce an error in that item's slot
- Network or upstream DNS resolver errors may populate per-item error fields
- Batch size exceeding 20 domains may be rejected or partially processed
- Ambiguous NS records that don't clearly match Hetzner patterns return false

## How this service works

Bulk is dns hosted by hetzner: up to 20 domains in one call, processed concurrently, results in input order with a per-item error field and a failure count. Same answer per item as the single endpoint. Batch enrichment for agents that hold a list. $0.10 per batch.

## Output

An ordered array of results matching the input domain list, where each item indicates whether that domain's DNS is hosted by Hetzner (based on NS record matching), plus a per-item error field if the lookup failed and an overall failure count for the batch.
