# is-dns-hosted-by-ns1-bulk

> is-dns-hosted-by-ns1-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).

Bulk-checks up to 20 domains concurrently to determine whether each domain's DNS is hosted by NS1, returning ordered results with per-item errors and a failure count.

## Facts

- Endpoint: GET https://dns.intel.rallylive.ca/bulk/dns/hosted-by/ns1?utm_source=zero.xyz
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-20
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/is-dns-hosted-by-ns1-bulk-e274c053
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_opOZmFCvzKum0hvLbAfPM

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-ns1-bulk-e274c053
```

Example prompt: Check all these domains at once and tell me which ones are hosted on NS1 DNS: example.com, acmecorp.io, widget.net, foobar.org — I need results for all of them together, not one by one.

## When to prefer this

Use this endpoint when you have a list of 2–20 domains and need to check NS1 hosting status for all of them efficiently in a single paid call, rather than making multiple sequential single-domain calls. Ideal for portfolio audits, migration planning, or vendor dependency scans where throughput and cost efficiency matter.

## Known failure modes

- Domain not resolvable or invalid — per-item error field populated
- NS record lookup timeout via Cloudflare DoH — counted in failure total
- Batch exceeds 20 domains — request rejected
- Payment not provided or insufficient — 402 response returned
- Partial batch failure — some items succeed, failed items increment failure count

## How this service works

Bulk is dns hosted by ns1: 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 NS1 (same answer as the single-domain endpoint), plus a per-item error field if the lookup failed, and an overall failure count for the batch.
