# DNS CNAME Record Bulk Lookup

> DNS CNAME Record Bulk Lookup is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Performs concurrent DNS CNAME record lookups for up to 20 hostnames in a single call, returning results in input order with per-item error fields 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 dns-cname-record-bulk-lookup-7dd34f30
```

Example prompt: Can you look up the CNAME records for all of these domains at once: example.com, cdn.mysite.io, mail.company.org, api.service.net, and static.brand.com?

## When to prefer this

Use this endpoint when you need CNAME records for multiple hostnames (2–20) and want to avoid making sequential single-domain calls. It processes domains concurrently and returns results in input order, making it ideal for bulk enrichment pipelines, security investigations, or onboarding verification flows where you hold a list of domains. For a single domain, prefer the /dns/cname sibling endpoint instead.

## Known failure modes

- Domain does not have a CNAME record (returns per-item error, not a top-level failure)
- Invalid or malformed hostname in the input list (per-item error returned)
- Batch exceeds 20 domains (request rejected)
- DNS resolution timeout for one or more items (per-item error with timeout indicator)
- Network connectivity issue reaching the DNS resolver (may result in all items erroring)

## How this service works

Bulk dns cname record: up to 20 domains in one call, processed concurrently, results returned in input order with a per-item error field and a count of failures. Same answer per item as the single /dns/cname endpoint (DNS CNAME record lookup for a hostname). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of results matching the input domain list, where each item contains the CNAME target (canonical hostname the domain aliases to) or a per-item error message if the lookup failed, plus a top-level count of how many items failed.
