## 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 td-com-downtime-change-watch-d34c2cd0
```

Example prompt: Keep an eye on td.com for me and let me know if its status changes — like if it goes down or comes back online — compared to the last time you checked.

## When to prefer this

Use this endpoint when you need change-aware monitoring of td.com specifically — it saves you from processing raw status data yourself by diffing against the prior result and flagging exactly what changed. Ideal for scheduling periodic checks and triggering alerts only on real status transitions, rather than polling a plain is-down endpoint and doing your own comparison.

## Known failure modes

- No previous check result stored — first call returns current status without a change comparison
- td.com check itself may fail if the domain is unreachable from the monitoring edge
- Stored comparison data expires after 90 days, resetting the baseline
- Payment failure ($0.02 USDC) prevents the check from running

## How this service works

Change watch for is td 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 uptime check result for td.com, a boolean indicating whether the status changed since the last call, the specific fields that changed along with their before and after values, and the timestamp of when the status was last observed. Results from previous calls are retained for 90 days.
