## 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 aws-aws-amazon-com-downtime-change-watch-48162e07
```

Example prompt: Check whether aws.amazon.com has gone down since I last asked, and tell me if anything changed — specifically what fields changed and what the before and after values were.

## When to prefer this

Choose this endpoint when you need change-detection semantics for AWS availability — not just a one-shot status check, but a comparison against your last known state. Ideal for scheduling periodic polls and triggering alerts only on state transitions (up→down or down→up) rather than on every check.

## Known failure modes

- No previous result stored (first call or >90 days since last call) — changed field may be null or baseline
- aws.amazon.com itself is unreachable — may return error or ambiguous down status
- Payment failure (x402) — call not processed, no result returned
- Stale comparison if prior call was made too long ago

## How this service works

Change watch for is aws amazon 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 aws.amazon.com, a boolean 'changed' flag indicating whether the result differs from the previous call (stored up to 90 days), the specific fields that changed with their before and after values, and the timestamp of when the status was last seen.
