Example prompt: Can you check whether alibaba.com has its email hosted by Alibaba Mail — look up the MX records and tell me if they match Alibaba Mail's mail-exchanger patterns?

## When to prefer this

Use this endpoint when you need a quick, affordable ($0.01) single-domain check to determine whether Alibaba Mail specifically is the MX provider, with transparent MX host data and match reasoning. Prefer this over generic MX lookup tools when you need Alibaba Mail provider detection with matched pattern details, or when automating sales, deliverability, or migration workflows at scale using per-domain checks.

## Known failure modes

- Domain does not exist or has no MX records — returns no match with empty MX list
- DNS lookup failure via Cloudflare DoH — may return an error or inconclusive result
- Domain uses a custom or vanity hostname masking Alibaba Mail — may return false negative
- Payment not fulfilled — request blocked with 402 response
- Transient network timeout reaching Cloudflare DoH — may require retry

## Output
