## 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-shopify-ca-down-watch-902c8b2a
```

Example prompt: Watch shopify.ca for me and tell me if its up/down status has changed since the last time you checked — I want to know what flipped and when.

## When to prefer this

Use this endpoint when you need change-detection semantics rather than a raw up/down ping — it persists your previous result for 90 days and returns a diff, making it ideal for scheduled polling workflows or alert pipelines that should only fire when something actually changes. Prefer it over a plain is-down check when you want to avoid repeat alerts on a persistent outage.

## Known failure modes

- No previous check stored — first call returns current status with no change comparison
- Previous check older than 90 days — baseline expired, treated as first call
- shopify.ca unreachable at check time — may return down status or network error
- Repeated calls within short window may show no change even if transient flap occurred

## How this service works

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