# ClouDNS Bulk Hosting Check

> ClouDNS Bulk Hosting Check is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-18).

Checks up to 20 domains at once to determine whether each domain's DNS is hosted by ClouDNS, returning concurrent results in input order with per-item errors and a failure count.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 cloudns-bulk-hosting-check-e385a558
```

Example prompt: Check all 20 domains in my list — example.com, mysite.org, testdomain.net, and the rest — and tell me which ones are using ClouDNS to host their DNS, with any errors flagged per domain.

## When to prefer this

Use this endpoint when you need to check whether multiple domains (up to 20) are hosted on ClouDNS in a single API call, rather than making individual requests per domain. Ideal for portfolio audits, competitor research, or pre-migration checks where efficiency matters. Choose the single-domain endpoint if you only need to check one domain and want to minimize cost ($0.10 per batch vs per-item pricing).

## Known failure modes

- Domain does not exist or has no NS records — per-item error returned, counted in failure total
- Batch exceeds 20 domains — likely rejected or truncated
- Cloudflare DoH lookup failure for one or more domains — reflected as per-item errors
- Malformed domain input — per-item error with failure count incremented
- Payment failure (x402) — entire batch call rejected before processing

## How this service works

Bulk is dns hosted by cloudns: 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

Returns an ordered array of results matching the input domain list, where each item contains a boolean indicating whether the domain's DNS is hosted by ClouDNS (based on NS record matching via Cloudflare DoH), a per-item error field if the lookup failed, and a summary failure count across the batch.
