# is-dns-hosted-by-rackspace-bulk

> is-dns-hosted-by-rackspace-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 up to 20 domains concurrently to determine if each one's DNS is hosted by Rackspace, returning results in input order with per-item error handling.

## 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-rackspace-bulk-891de632
```

Example prompt: Check these 15 domains for me and tell me which ones have their DNS hosted by Rackspace: example.com, acme.io, foobar.net, ... — I need all results in the same order I gave them.

## When to prefer this

Use this endpoint when you have 2–20 domains and need to efficiently check Rackspace DNS hosting in a single call rather than making multiple single-domain requests. It is ideal for portfolio audits, vendor dependency checks, and pre-migration assessments. Prefer the single-domain endpoint when checking only one domain to avoid unnecessary batching overhead.

## Known failure modes

- Domain not found or invalid domain name returns a per-item error rather than a top-level failure
- Network or DNS resolution timeout for a specific domain populates that item's error field
- Batch exceeds 20 domains may be rejected or truncated
- Malformed input results in a 4xx error for the entire request
- DNS provider detection may be inconclusive for domains with unusual NS configurations

## How this service works

Bulk is dns hosted by rackspace: 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 per-domain results matching the input order, each containing whether the domain's DNS is hosted by Rackspace (boolean or equivalent indicator), a per-item error field if the lookup failed, and an overall failure count for the batch.
