# Battle.net Down Change Watch

> Battle.net Down 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 Battle.net is down, returns the current status plus a change flag and before/after field diffs compared to your previous check (stored 90 days).

- Price: $0.02/call
- Payment: x402

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 battle-net-down-change-watch-abadabad
```

Example prompt: Keep an eye on Battle.net for me — check if it's down and let me know whether the status has changed since the last time you checked.

## When to prefer this

Choose this endpoint when you need change detection rather than just a point-in-time status check — it automatically diffs the current Battle.net status against your last call, so you only act when something actually changes. Ideal for scheduling periodic polls and triggering alerts on state transitions. Use the sibling is-battle-net-down endpoint if you only need a single live check with no change comparison.

## Known failure modes

- Battle.net itself is unreachable — endpoint may still return a result indicating a down state
- No previous check stored (first call) — 'changed' may default to false or null with no diff
- Stale previous result if >90 days since last call — baseline is lost
- Rate or payment errors if the $0.02 USDC x402 payment is not properly attached

## How this service works

Change watch for is battle net 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 Battle.net, a boolean 'changed' flag indicating whether the result differs from the previous call, the specific fields that changed with before and after values, and the timestamp of when the status was last observed. Previous check results are retained for 90 days per query.
