## 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 expedia-com-downtime-change-watch-ab9931b7
```

Example prompt: Keep an eye on whether expedia.com is up or down and let me know the moment its status changes compared to last time you checked.

## When to prefer this

Choose this endpoint when you need change-aware monitoring of expedia.com specifically — not just a one-shot status check — and want to detect transitions (up→down or down→up) with before/after diffs. Ideal for scheduling recurring checks and triggering alerts only on state changes rather than polling raw status repeatedly.

## Known failure modes

- No prior check result stored yet (first call returns current state only, no diff)
- Prior result expired after 90 days (diff unavailable)
- Expedia.com may be reachable from Cloudflare edge but not from user's region (false negative)
- Network timeout or edge error causes check failure
- Payment failure ($0.02 USDC x402) blocks the call

## How this service works

Change watch for is expedia 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 expedia.com, a boolean 'changed' field indicating whether the result differs from the previous call, an object listing fields that changed with their before and after values, and the timestamp of when the status was last seen. The previous result is retained for 90 days per query.
