# is-amazon-ca-down-watch

> is-amazon-ca-down-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 Amazon.ca is currently down and detects changes in its availability status compared to a previous check, returning a diff with before/after values.

## 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 is-amazon-ca-down-watch-f650f9f1
```

Example prompt: Keep an eye on Amazon.ca for me — check if it's down right now and let me know if anything has changed since the last time you checked.

## When to prefer this

Choose this endpoint when you need change-detection semantics — not just a one-off status check, but an alert when Amazon.ca's availability actually shifts. Ideal for scheduled agents that poll on a recurring basis and only need to act when something changes. Prefer this over a plain is-down check when you want diff output (before/after field values) and a persistent comparison baseline across calls.

## Known failure modes

- Amazon.ca URL check itself may fail transiently due to network issues, returning an inconclusive status
- No previous check stored (first call in 90-day window) may result in 'changed: false' or null diff
- Service may return stale comparison if 90-day history has expired
- The $0.02 USDC payment may fail if the x402 payment header is missing or insufficient

## How this service works

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