# is-dns-hosted-by-ionos-bulk

> is-dns-hosted-by-ionos-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 2026-10-18).

Checks whether up to 20 domains' DNS is hosted by IONOS in a single concurrent batch call, returning per-item results in input order with error fields and a failure count.

## Facts

- Endpoint: GET https://dns.intel.rallylive.ca/bulk/dns/hosted-by/ionos?utm_source=zero.xyz
- Price: $0.1/call
- Payment: x402
- Status: unknown

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_4ZYAUl-lhO8piNo0zeVx2

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 is-dns-hosted-by-ionos-bulk-512b5354
```

Example prompt: Can you check whether these 15 domains — example.com, myshop.de, acmecorp.net, (and 12 more) — have their DNS hosted by IONOS? I need the result for each domain and a count of any failures.

## When to prefer this

Use this endpoint when you have a list of 2–20 domains and need to check IONOS DNS hosting status efficiently in a single call rather than making multiple sequential single-domain requests. Prefer it over the single-domain endpoint whenever you hold a batch of domains, as it processes them concurrently and returns results in input order with structured per-item errors.

## Known failure modes

- DNS resolution failure for one or more domains — per-item error field populated, failure count incremented
- Invalid or malformed domain names in the batch cause item-level errors
- Batch exceeds 20 domains — request rejected or truncated
- Cloudflare DoH lookup timeout for specific domains
- Network connectivity issues to dns.intel.rallylive.ca returning HTTP error
- Payment not fulfilled (x402) — request blocked

## How this service works

Bulk is dns hosted by ionos: 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

A list of per-item results in the same order as the input domains, each containing whether that domain's DNS is hosted by IONOS (matching NS records via Cloudflare DoH), any per-item error message, and an overall failure count for the batch.
