Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 aa-com-downtime-change-watch-217a63d1
```

Example prompt: Keep an eye on aa.com for me and let me know as soon as its status changes — whether it goes down or comes back up — compared to where it was last time you checked.

## When to prefer this

Use this endpoint when you need change-detection semantics rather than just a raw status check — i.e., you want to know not just whether aa.com is down, but whether its status has changed since you last polled. Ideal for scheduling periodic monitors that only fire alerts on transitions, avoiding alert fatigue from repeated identical results.

## Known failure modes

- No previous result stored (first call returns current status with no change comparison)
- aa.com check times out due to network issues at the edge
- Stale history if >90 days since last call, losing diff baseline
- Payment failure if wallet has insufficient USDC balance ($0.02 per call)
- False 'up' result if aa.com returns a non-error status page during partial outage

## How this service works

Change watch for is aa 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 status of aa.com, a boolean 'changed' flag indicating whether it differs from the previous call's result, a diff of which fields changed with before and after values, and the timestamp of when the status was last observed. Previous results are retained for 90 days for comparison.
