## 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 hushmail-email-hosting-change-watch-f7253a65
```

Example prompt: Keep an eye on acmecorp.com and let me know if its email hosting status on Hushmail ever changes — I want to catch the moment they switch to or away from Hushmail.

## When to prefer this

Use this endpoint when you need to be alerted to changes in Hushmail email hosting status over time rather than just a one-time point-in-time check. It is ideal for scheduled polling workflows where detecting the transition moment (changed=true) is the goal. Prefer this over the plain check endpoint when you want diff-aware results with before/after values and a 90-day comparison window.

## Known failure modes

- Domain not provided or invalid — missing required query parameter
- DNS lookup failure — Cloudflare DoH unavailable or timeout
- No previous check stored — first call returns no comparison data (no 'changed' diff)
- Domain has no MX records — cannot determine hosting
- Payment failure — insufficient USDC balance for $0.02 per call charge

## How this service works

Change watch for is email hosted by hushmail: 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. Schedule it to be alerted when this changes. $0.02 per check.

## Output

Returns the current Hushmail hosting status for the domain, a boolean 'changed' flag indicating whether the result differs from the previous check (stored up to 90 days), the specific fields that changed with before/after values, and the timestamp of when the status was last seen.
