## How to call it through Zero

```sh
zero fetch --capability planetscale-is-down-change-watch-aad570e5
```

Example prompt: Can you check if PlanetScale is down right now, and let me know whether its status has changed since the last time you checked?

## When to prefer this

Choose this endpoint when you need to detect *changes* in PlanetScale's availability over time rather than just a point-in-time check. It is ideal for scheduling periodic polling workflows where you only want to act when the status flips, because it automatically compares against the previous result and surfaces exactly what changed and when.

## Known failure modes

- Network error reaching planetscale.com — may report false downtime
- No previous call stored yet — changed flag may be null or treated as first-seen
- Payment failure (x402) — request rejected before check runs
- Stale cache if 90-day window not hit — returns last known state

## How this service works

Change watch for is planetscale 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 up/down answer for planetscale.com, a boolean 'changed' flag indicating whether the result differs from the previous call, a list of fields that changed with their before and after values, and a timestamp of when the status was last seen. Previous results are retained for 90 days per query.
