## 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 gm-com-downtime-change-watch-fd9aa07e
```

Example prompt: Keep an eye on gm.com for me — let me know if its availability status changes compared to the last time you checked.

## When to prefer this

Choose this endpoint when you need change detection — not just a point-in-time status — for gm.com. It is ideal for scheduled polling workflows where you want to be alerted only when something changes, avoiding noise from repeated identical results. If you only need the current status without diffing, use the non-watch variant instead.

## Known failure modes

- No previous check stored (first call returns no diff, only current state)
- gm.com itself is unreachable causing check to fail
- Payment not processed (x402 payment required, $0.02 USDC per call)
- Stale baseline if more than 90 days since last call (comparison window expires)

## How this service works

Change watch for is gm 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 availability status of gm.com, a boolean indicating whether anything changed since the last call for this query, a diff of changed fields with before and after values, and the timestamp of when the status was last observed. Results from previous calls are retained for 90 days for comparison.
