## 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 stability-ai-uptime-change-watch-210ae4f4
```

Example prompt: Keep an eye on Stability AI for me — let me know if its availability status changes compared to the last time you checked, and tell me exactly what's different.

## When to prefer this

Use this endpoint when you need change-detection semantics — not just whether Stability AI is currently down, but whether its status has changed since your last check. Ideal for scheduling periodic polling workflows where you only want to act on transitions (up→down or down→up), rather than reading the raw current status every time.

## Known failure modes

- No previous check stored — first call has no baseline to compare against, so 'changed' may be null or false by default
- stability.ai unreachable — edge check itself may time out or return an error status
- Stale baseline — if 90 days have elapsed since last call, the prior result is purged and comparison resets
- Payment failure — $0.02 USDC x402 payment required; if not included the request is rejected

## How this service works

Change watch for is stability ai 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 uptime answer for stability.ai, a boolean 'changed' flag indicating whether the status differs from the previous call, a list of fields that changed with before/after values, and a timestamp of when it was last seen. Previous results are retained for 90 days for comparison.
