## 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-runbox-watch-f55a00a2
```

Example prompt: Keep an eye on whether acme.com is hosted by Runbox and let me know if anything changes — I want to be alerted the moment their email hosting switches.

## When to prefer this

Use this endpoint when you need to continuously monitor whether a specific domain is hosted by Runbox and want change detection built in — ideal for scheduled polling workflows where you only need to act when the hosting status changes. Prefer over a plain one-shot check when you want before/after diff tracking without managing state yourself.

## Known failure modes

- Domain not provided or invalid — query param missing leads to error response
- Domain has no MX records — returns false with no change data
- Previous result not found (first call or >90 days since last call) — no comparison available, changed may be false or undefined
- DNS lookup timeout via Cloudflare DoH — transient failure
- Rate limiting or payment failure — 402 response if USDC payment not attached

## How this service works

Change watch for is email hosted by runbox: 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 Runbox email hosting status (true/false), a changed flag indicating whether the result differs from the previous call, the specific fields that changed with before and after values, and the timestamp of when the status was last seen. Results are compared against the stored state from your previous call, retained for 90 days.
