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-barracuda-watch-356293d3
```

Example prompt: Keep an eye on whether acmecorp.com is hosted by Barracuda email and let me know if that status has changed since the last time we checked — show me what changed and when it was last seen.

## When to prefer this

Use this endpoint when you need change detection specifically for Barracuda email hosting rather than a simple one-off check. It is ideal for scheduled monitoring workflows where you want to be alerted only when hosting status shifts, avoiding noise from repeated identical results. Prefer it over the single-check variant when building automation pipelines or alerting systems that need diff-aware responses with before/after context.

## Known failure modes

- Domain not previously checked — no historical baseline available, so 'changed' cannot be determined on first call
- Invalid or malformed domain input — endpoint may return an error or null result
- Domain DNS lookup failure — transient network issues may cause indeterminate results
- 90-day retention window expired — if more than 90 days since last check, historical comparison is lost

## How this service works

Change watch for is email hosted by barracuda: 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 indicating whether the domain's email is hosted by Barracuda, a 'changed' true/false flag comparing against the previous call result (retained for 90 days), a list of fields that changed with before/after values, and the timestamp of when the status was last seen.
