# is-dns-hosted-by-azure-dns-bulk

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

Bulk-checks whether up to 20 domains are hosted on Azure DNS by inspecting their NS records, returning concurrent results in input order with per-item error fields.

## Facts

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

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-azure-dns-bulk-12a7f4f8
```

Example prompt: Can you check whether these 20 domains are all hosted on Azure DNS and tell me which ones aren't, along with any errors?

## When to prefer this

Choose this endpoint over the single-domain variant when you need to check more than one domain and want to minimize API calls and cost — it processes up to 20 domains concurrently in a single $0.10 call instead of paying per-domain. Prefer this for batch enrichment pipelines, DNS audits, migration assessments, or any workflow where an agent holds a list of domains and needs Azure DNS status for all of them efficiently.

## Known failure modes

- Domain not found or invalid — per-item error field set, domain excluded from positive count
- DNS resolution timeout from upstream Cloudflare DoH — per-item error populated
- More than 20 domains submitted — batch limit exceeded error
- Payment not received or x402 auth failure — request rejected before processing
- Network error reaching Cloudflare DoH — failure count incremented

## How this service works

Bulk is dns hosted by azure dns: 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 (one per input domain) each containing a boolean indicating whether the domain's NS records resolve to Azure DNS name servers, plus a per-item error field for any lookup failures, and an overall failure count for the batch.
