## How to call it through Zero

```

Example prompt: Keep an eye on aircanada.com for me and let me know the moment its up/down status changes — I want to know if it goes down or comes back up, with what specifically changed.

## When to prefer this

Use this endpoint when you need change-detection semantics — you want to know not just whether aircanada.com is up, but whether its status has changed since your last check. Ideal for scheduled polling workflows that only need to act on transitions (up→down or down→up) rather than every raw status check.

## Known failure modes

- No previous check stored (first call or older than 90 days) — changed field may be null or defaulted
- Network error reaching aircanada.com from Cloudflare edge — may return error status rather than up/down result
- Payment failure for $0.02 USDC — request not processed
- Cloudflare edge connectivity issue — response time or status data unavailable

## How this service works

Change watch for is aircanada com down: runs the check, compares it with the result from your previous call for the same query (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 up/down answer for aircanada.com, a boolean indicating whether the status changed since the previous call (stored up to 90 days), a list of fields that changed with before and after values, and a timestamp of when the status was last observed.
