## How to call it through Zero

```sh
zero fetch --capability is-email-hosted-by-hushmail-1d15dd12
```

Example prompt: Can you check if the domain example.com has its email hosted by Hushmail — I need to know if their MX records match Hushmail's mail exchangers?

## When to prefer this

Use this endpoint when you need a fast, low-cost single-domain check specifically to detect Hushmail as the email hosting provider. Prefer this over generic MX lookup tools when you want the Hushmail pattern matching done for you without manual inspection. Choose the bulk sibling endpoint when checking multiple domains at once to reduce cost and latency.

## Known failure modes

- Domain does not exist or has no MX records — returns no match with empty MX list
- Cloudflare DoH lookup failure due to network issues — may return an error or timeout
- Invalid or malformed domain input — likely returns an error response
- Domain uses a mail relay or forwarder masking Hushmail — may return false negative
- Rate limiting or payment failure — request rejected before lookup is performed

## How this service works

Is the domain's email hosted by hushmail? Looks up the MX records (Cloudflare DoH) and matches them against hushmail's mail-exchanger patterns, returning yes/no, the MX hosts and which matched. Provider detection for deliverability, sales and migration work. $0.01 per lookup.

## Output

Returns a yes/no answer indicating whether the domain's email is hosted by Hushmail, along with the full list of MX hosts discovered via Cloudflare DoH and which specific MX records matched Hushmail's known mail-exchanger patterns.
