## How to call it through Zero

```sh
zero fetch --capability medium-com-uptime-change-watch-5e039d68
```

Example prompt: Keep an eye on Medium.com for me and let me know if its up/down status changes from what it was the last time you checked.

## When to prefer this

Use this endpoint when you need change-aware uptime monitoring for Medium.com specifically — it automatically diffs the current status against your last call so you only act on actual state changes, rather than polling raw status and comparing yourself. Ideal for scheduling periodic checks and triggering alerts only when something actually changes.

## Known failure modes

- No previous check stored (first call returns current state only with no diff)
- Medium.com is unreachable due to transient network issues causing false positives
- Stored previous result expired after 90 days, losing change baseline
- Payment not processed resulting in HTTP 402 and no check performed

## How this service works

Change watch for is medium 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 Medium.com, a boolean 'changed' flag indicating whether status differs from the previous call, a list of fields that changed with their before and after values, and the timestamp of when the status was last observed. Previous call result is retained for 90 days per query.
