> Mimecast Email Hosting Watch is a paid API for AI agents from email.intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-24).

## 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 mimecast-email-hosting-watch-724736a6
```

Example prompt: Keep an eye on acmecorp.com and let me know if their email hosting by Mimecast changes — I want to be alerted whenever the answer flips compared to the last time we checked.

## When to prefer this

Choose this endpoint when you need to detect changes in Mimecast email hosting status over time rather than just a one-off check. It is ideal for scheduled monitoring workflows, alerting pipelines, and sales or security intelligence use cases where knowing when a domain's email provider changes is more valuable than knowing the current state alone. Use over a plain lookup endpoint when change detection and before/after diffing are required.

## Known failure modes

- Domain not previously checked — no comparison baseline available, only current result returned
- Invalid or malformed domain input — returns an error
- Domain DNS lookup failure — unable to determine hosting status
- Rate limiting or payment failure — $0.02 USDC per call required via x402
- Stale baseline — if more than 90 days have passed since last check, prior result is expired and no diff is available

## How this service works

Change watch for is email hosted by mimecast: 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 Mimecast hosting status (true/false), a 'changed' boolean indicating whether the result differs from the previous call for the same domain, an object listing fields that changed with before/after values, and a timestamp of when the previous state was last seen. Previous results are retained for 90 days.
