> CNN.com Uptime 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).

## 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 cnn-com-uptime-change-watch-a21b3115
```

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

## When to prefer this

Choose this endpoint when you need to detect changes in CNN.com's availability over time rather than just its current status. It is specifically useful for scheduling periodic polls and triggering workflows only when something changes, avoiding alert fatigue from repeated identical results. Prefer this over a raw uptime check when you need diff tracking, before/after values, and 90-day state persistence.

## Known failure modes

- No previous result stored (first call or data expired after 90 days): 'changed' may be null or false with no diff
- CNN.com unreachable due to network issues on the checker's end: may return false negative
- Payment not processed (x402 protocol failure): request rejected before check runs
- Transient HTTP errors from CNN.com may produce inconsistent up/down readings

## How this service works

Change watch for is cnn 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 cnn.com, a boolean 'changed' flag indicating whether the result differs from the previous stored check, a list of fields that changed with their before and after values, and a timestamp of when the status was last seen. Previous results are retained for 90 days.
