Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-web-de-watch-017ebf93
```

Example prompt: Keep an eye on whether freundin.de is still hosted by Web.de for email — let me know if anything changes from last time you checked.

## When to prefer this

Use this endpoint when you need to continuously monitor a specific domain to detect if its email hosting switches to or from Web.de, rather than just performing a one-time check. It is ideal for scheduled agent workflows that need change-alerting semantics with before/after diffs. Prefer the non-watch variant for a simple point-in-time lookup, and prefer this watch variant when you want to be notified only when something changes.

## Known failure modes

- Domain not provided or malformed — returns error
- MX record lookup fails due to DNS unavailability — may return inconclusive result
- No prior result exists for the domain (first call) — 'changed' field will be false or null
- Domain has no MX records — hosted-by check returns false

## How this service works

Change watch for is email hosted by web de: 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 Web.de, a 'changed' true/false flag indicating whether the result differs from the previous call for that domain, an array of changed fields with before and after values, and a timestamp of when the state was last seen. Previous results are retained for 90 days.
