## 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-ionos-mail-watch-7bcd355a
```

Example prompt: Keep an eye on whether example.com is hosted by IONOS Mail and let me know if anything changes compared to last time you checked.

## When to prefer this

Use this endpoint when you need to continuously monitor whether a specific domain's email is hosted by IONOS Mail and want diff-aware change detection rather than just a point-in-time lookup. Ideal for scheduled agent workflows that need to be alerted to email provider migrations without storing state themselves, since the service retains the previous result for 90 days. Prefer the non-watch variant for one-off checks, or the bulk variant if checking many domains simultaneously.

## Known failure modes

- Domain not provided or malformed — missing required query parameter
- DNS lookup failure via Cloudflare DoH — upstream resolution error
- No previous check stored (first call for a domain) — changed field may be null or false by default
- Payment failure — x402 payment not completed, request rejected
- Rate limiting or network timeout from upstream DNS provider

## How this service works

Change watch for is email hosted by ionos 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 IONOS Mail, a 'changed' true/false flag indicating if the result differs from the previous check (stored for 90 days), the specific fields that changed with before/after values, and a timestamp of when the status was last seen.
