# is-dns-hosted-by-alibaba

> is-dns-hosted-by-alibaba is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Checks whether a domain's DNS is hosted by Alibaba Cloud by querying NS records via Cloudflare DoH and matching against Alibaba nameserver patterns, returning a yes/no result, the full NS list, and which ones matched.

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-alibaba-728cdfb4
```

Example prompt: Can you check if the DNS for alibaba-cloud-test.com is hosted by Alibaba Cloud — I need to know whether they're using Alibaba nameservers and which ones matched?

## When to prefer this

Choose this endpoint when you need to programmatically determine whether a specific domain's DNS is managed by Alibaba Cloud, particularly for sales intelligence (finding Alibaba customers), security assessments (mapping vendor infrastructure), or pre-migration audits. It is more specific than a generic NS lookup because it performs the Alibaba pattern-matching logic for you. Prefer the sibling AWS Route 53 endpoint if you need to check for Amazon DNS instead.

## Known failure modes

- Domain does not exist or has no NS records — returns empty result or NXDOMAIN
- Cloudflare DoH unreachable — lookup fails with a connectivity error
- Domain uses Alibaba DNS under an unrecognized pattern — false negative (not matched)
- Invalid domain format provided — request rejected
- Rate limiting or payment failure — 402 response if USDC payment not attached

## How this service works

Is the domain's DNS hosted by alibaba? Looks up the NS records (Cloudflare DoH) and matches them against alibaba's nameserver patterns, returning yes/no, the nameservers and which ones matched. Vendor detection for sales, migration and security work. $0.01 per lookup.

## Output

Returns a yes/no indicator of whether the domain's DNS is hosted by Alibaba, the full list of NS records retrieved via Cloudflare DoH, and the subset of nameservers that matched Alibaba's known nameserver patterns.
