## 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 wayfair-uptime-change-watcher-59068baa
```

Example prompt: Keep an eye on wayfair.com for me — run a check now and tell me if its status has changed since the last time you checked, including what exactly changed.

## When to prefer this

Choose this endpoint when you need change-detection semantics rather than a raw status snapshot — specifically when you want to know whether wayfair.com's availability has shifted since your last poll. It is ideal for agents that schedule recurring checks and only want to act on transitions (up→down or down→up), since it handles state storage and diff computation automatically without requiring the caller to maintain history.

## Known failure modes

- Network unreachable — check itself fails and no comparison is possible
- No previous result stored (first call) — 'changed' may be null or false with no diff
- 90-day history expired — previous baseline lost, comparison resets
- Wayfair.com returns ambiguous intermediate state (e.g. partial response) — status may be misclassified
- Payment failure for $0.02 USDC — request rejected before check runs

## How this service works

Change watch for is wayfair 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 wayfair.com, a boolean 'changed' flag indicating whether the result differs from the previous call, a list of fields that changed with their before and after values, and the timestamp of when the status was last seen. The previous result is stored and compared over a 90-day window.
