## 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 loblaws-ca-uptime-change-watch-8e90e5aa
```

Example prompt: Keep an eye on loblaws.ca for me and let me know as soon as its up-or-down status changes from what it was last time you checked.

## When to prefer this

Choose this endpoint when you need differential monitoring of loblaws.ca specifically — i.e., you want to know not just whether it is up or down right now, but whether that status has changed since your last poll. It is ideal for scheduling periodic checks and triggering alerts only on state transitions, avoiding alert fatigue from repeated same-state results.

## Known failure modes

- No previous result stored yet (first call returns current state with changed=false or null baseline)
- loblaws.ca temporarily unreachable due to transient network issue causing false positive down status
- Stale 90-day cache eviction means change comparison resets
- Payment failure or insufficient USDC balance blocks the check

## How this service works

Change watch for is loblaws ca 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 loblaws.ca, a boolean 'changed' flag indicating whether status differs from the previous call, a list of fields that changed with before/after values, and a timestamp of when the status was last observed. Historical state is retained for 90 days per query.
