Example prompt: Keep an eye on square.com for me — run a check and tell me if its up/down status has changed since the last time you checked, and what specifically changed.

## When to prefer this

Choose this endpoint when you need change detection for square.com specifically — not just a live status check but a stateful comparison against a previous result. Ideal for scheduling periodic polls and triggering alerts only when something actually changes, rather than re-processing identical results every time.

## Known failure modes

- No prior check stored — first call returns current status with no diff (changed: false or null baseline)
- square.com check itself fails due to network issues — may return error or indeterminate status
- Stored result expired (older than 90 days) — treated as no prior result, no diff available
- Upstream HTTP check timeout — response time data may be missing

## How this service works

Change watch for is square 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 status of square.com, a boolean 'changed' field indicating whether the result differs from the previous call (stored up to 90 days), a diff of any changed fields with before/after values, and a timestamp of when the status was last observed.
