# is-dns-hosted-by-linode-bulk

> is-dns-hosted-by-linode-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 the DNS for up to 20 domains is hosted by Linode, returning per-item results concurrently in input order with error details and a failure count.

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-linode-bulk-5658391e
```

Example prompt: Check all 15 of these domains at once and tell me which ones have their DNS hosted by Linode — here's the list: example.com, mysite.io, another.net... I want to see a result for each one plus a count of any failures.

## When to prefer this

Choose this endpoint when you have a list of 2–20 domains and need to check Linode DNS hosting for all of them in a single call rather than making individual requests per domain. It is ideal for bulk enrichment workflows, infrastructure audits, and dataset annotation where concurrency and ordered results matter. Use the single-domain endpoint instead when only one domain needs checking.

## Known failure modes

- One or more domains in the batch fail DNS resolution, surfaced in the per-item error field
- Batch exceeds 20 domain limit, resulting in a request error
- Invalid domain format causes per-item failure
- Cloudflare DoH upstream timeout produces partial results with failure count incremented
- Payment not completed via x402, returning 402 status before any lookup is performed

## How this service works

Bulk is dns hosted by linode: 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 list of per-domain results indicating whether each domain's DNS is hosted by Linode, a per-item error field for any lookup failures, and an overall failure count for the batch.
