## 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-realtor-ca-down-watch-36187081
```

Example prompt: Keep an eye on realtor.ca for me — let me know as soon as its status changes from what it was last time you checked, including exactly what field changed and whether it went down or came back up.

## When to prefer this

Choose this endpoint when you need to detect state changes in realtor.ca's availability over time rather than just a one-time status check. It is ideal for scheduled polling workflows where you want diff-based alerting — it tells you not just the current status but whether anything changed and what specifically changed, saving you from having to store and compare results yourself.

## Known failure modes

- No previous result stored (first call returns changed=false or baseline only)
- realtor.ca unreachable from edge — may reflect a real outage or a network issue
- Stored comparison expired after 90 days, losing historical baseline
- Payment of $0.02 USDC not processed — request rejected

## How this service works

Change watch for is realtor 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 HTTP status and availability of realtor.ca, a boolean 'changed' flag indicating whether anything differs from the previous call's result (stored for 90 days), a list of fields that changed with their before and after values, and a timestamp of when the status was last seen.
