## 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-hey-watch-608d4e60
```

Example prompt: Watch the domain rallylive.ca and alert me if it ever switches to or from Hey email hosting — I want to know the moment the status changes compared to last time you checked.

## When to prefer this

Choose this endpoint when you need to detect changes in Hey email hosting over time rather than just a one-time check. It is ideal for scheduled monitoring workflows where you want to be alerted when a domain starts or stops using Hey, with structured before/after change data. Prefer the non-watch version for simple one-off checks, or the bulk endpoint if checking many domains simultaneously.

## Known failure modes

- Domain not provided or invalid — missing required query parameter
- No previous check stored (first-time call) — 'changed' may be null or baseline
- DNS resolution failure — upstream Cloudflare DoH lookup error
- Rate limiting or payment failure — x402 payment not accepted
- Domain has no MX records — result defaults to false with no hosting detected

## How this service works

Change watch for is email hosted by hey: 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 result of whether the domain's email is hosted by Hey, a 'changed' true/false flag comparing to the previous check (stored 90 days), the specific fields that changed with before/after values, and the timestamp of when the result was last seen.
