# Zoom.us Downtime Change Watch

> Zoom.us Downtime Change Watch is a paid API for AI agents from monitor.intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-02).

Monitors whether zoom.us is down, compares current status to the previous check, and returns what changed and when — enabling scheduled alerting on status transitions.

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 zoom-us-downtime-change-watch-35360e27
```

Example prompt: Check if zoom.us is down and tell me whether the status has changed since the last time I checked — I want to know what changed and when it was last seen.

## When to prefer this

Choose this endpoint when you need change-aware monitoring of zoom.us — specifically when you want to know not just the current status but whether it has flipped since your last check, with field-level diffs. Ideal for scheduled polling automations and alert pipelines that should only fire on transitions, not on every check.

## Known failure modes

- No previous check stored (first call returns current result with no diff)
- Zoom.us check itself times out or is unreachable from edge
- Stored result expired (older than 90 days, treated as first call)
- Payment failure at $0.02 USDC per call blocks execution

## How this service works

Change watch for is zoom us 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 zoom.us, a boolean indicating whether the status changed since the last call, a diff of fields that changed with before and after values, and the timestamp of when the status was last observed — all based on a live edge check compared against a stored result kept for up to 90 days.
