Example prompt: Can you check whether acme.com uses Intercom Mail for its email hosting? I want to know if their MX records match Intercom's mail exchanger patterns.

## When to prefer this

Use this endpoint when you specifically need to detect whether a domain uses Intercom Mail as its email provider, particularly for sales intelligence, email deliverability analysis, or migration planning. It is purpose-built for Intercom Mail detection using live MX record lookups rather than cached or static data.

## Known failure modes

- Domain not found or invalid domain returns no MX records
- Cloudflare DoH lookup failure returns an error
- Domain has MX records but none match Intercom Mail patterns, returning 'no'
- Missing or malformed query parameter causes request failure
- Rate limiting or payment failure prevents lookup

## How this service works

Is the domain's email hosted by intercom mail? Looks up the MX records (Cloudflare DoH) and matches them against intercom-mail'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 Intercom Mail, along with the full list of MX hosts discovered via Cloudflare DoH and which specific hosts matched Intercom's mail-exchanger patterns.
