## 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-hetzner-mail-watch-99b7ac7b
```

Example prompt: Keep an eye on example.com and let me know if it ever stops — or starts — being hosted by Hetzner Mail; compare it against the last result you have on file.

## When to prefer this

Choose this endpoint when you need change-detection semantics for Hetzner Mail hosting rather than a simple point-in-time lookup. It is ideal for scheduled polling workflows where you want to be alerted only when the email hosting status actually changes, without storing state yourself. Prefer it over the non-watch variant when you need before/after diffs and a changed flag out of the box.

## Known failure modes

- Domain not provided or invalid format — missing required query parameter
- No previous result stored (first call) — 'changed' field may be null or baseline-only
- DNS resolution failure via Cloudflare DoH — MX lookup unavailable
- Payment not completed (x402) — endpoint returns 402 before processing
- Stored result expired (>90 days since last call) — no comparison baseline available

## How this service works

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

## Output

Returns the current boolean answer for whether the domain's email is hosted by Hetzner Mail, a 'changed' true/false flag comparing against the previous call result (stored for 90 days), the specific fields that changed with before and after values, and a timestamp of when the status was last seen.
