## 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-email-hosted-by-intercom-mail-change-watch-1d1d1ad2
```

Example prompt: Keep an eye on whether acmecorp.com's email is hosted by Intercom Mail and let me know if that status changes compared to the last time you checked.

## When to prefer this

Choose this endpoint when you need to detect changes in Intercom Mail email hosting over time, rather than just a one-time lookup. It is ideal for scheduled polling workflows, sales intelligence pipelines watching for prospect tool adoption, or compliance monitoring where you need before/after audit trails. If you only need a single point-in-time check with no change detection, use the non-watch variant instead.

## Known failure modes

- Domain not supplied or malformed — request fails with validation error
- No previous check stored (first call) — 'changed' will be false or undefined, no before/after diff available
- DNS lookup failure via Cloudflare DoH — result may be inconclusive
- Domain has no MX records — hosted-by result returns false
- Stale cache beyond 90-day retention window — treated as a fresh first check

## How this service works

Change watch for is email hosted by intercom mail: runs the check, compares it with the result from your previous call for the same domain (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen.

## Output
