## 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-shop-app-down-watch-61e48954
```

Example prompt: Check if shop.app is currently down and let me know if the status has changed since the last time you checked.

## When to prefer this

Choose this endpoint when you need to detect changes in shop.app's availability over time, not just a one-off status check. It is ideal for scheduled polling workflows where you want to be alerted only when the status changes, avoiding alert fatigue from repeated identical results. Prefer this over a simple ping check when you need a diff of exactly what changed and when.

## Known failure modes

- Previous check result not found if first call or data expired after 90 days — 'changed' flag may not be meaningful
- Network timeout if shop.app itself is unreachable in an ambiguous way
- Payment failure if USDC balance is insufficient for the $0.02 per check fee
- Stale comparison if the 90-day retained result has expired

## How this service works

Change watch for is shop app 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 shop.app, a boolean 'changed' flag indicating whether the result differs from the previous call (retained for 90 days), a diff object showing which fields changed with their before and after values, and the timestamp of when the status was last seen.
