## 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 bmo-com-downtime-change-watch-d0ae6a0c
```

Example prompt: Check if BMO.com is down right now and let me know if the status has changed since the last time you checked — I want to see what fields changed and when it was last seen up.

## When to prefer this

Choose this endpoint when you need change-aware uptime monitoring for BMO.com specifically — it handles state diffing so you don't have to track previous results yourself. Ideal for scheduled polling agents that only need to act when something changes, rather than on every check. Prefer alternatives if you need multi-region checks, historical trend data, or monitoring of a different site.

## Known failure modes

- No previous result stored (first call returns no diff)
- BMO.com check itself times out or errors, producing an indeterminate status
- Previous result expired after 90 days, losing comparison baseline
- Payment of $0.02 USDC not processed, blocking the check
- Network error reaching BMO.com from the monitor's location
