## 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 bbc-com-downtime-change-watch-2e7234e1
```

Example prompt: Check if BBC.com is down right now and tell me whether its status has changed since my last check — flag what's different and when it was last seen.

## When to prefer this

Use this endpoint when you need to detect changes in BBC.com's availability over time rather than just a one-shot status check. It is ideal for scheduled agents that want to be alerted only when something changes, avoiding noisy repeated notifications. Choose this over a plain uptime check when you need before/after diff data and change timestamps.

## Known failure modes

- No previous check stored (first call returns no diff)
- Previous result expired after 90 days causing diff loss
- bbc.com check itself times out or is unreachable from the monitor
- Payment failure (x402) prevents check from executing
- Stale cached state if bbc.com changes faster than polling interval

## How this service works

Change watch for is bbc 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 bbc.com, a boolean 'changed' flag indicating whether the result differs from your previous call (stored up to 90 days), a list of fields that changed with their before and after values, and a timestamp for when the status was last seen.
