# is-yahoo-com-down-watch

> is-yahoo-com-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).

Checks if yahoo.com is currently down, compares the result to the previous check (stored 90 days), and returns whether the status has changed with before/after field diffs.

## 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-yahoo-com-down-watch-adf266f4
```

Example prompt: Check if yahoo.com is currently down and let me know if anything has changed since the last time you checked — I want to know exactly what flipped and when.

## When to prefer this

Use this endpoint when you need stateful change detection for yahoo.com specifically — not just a point-in-time ping. It is ideal for scheduled polling workflows where you want to be notified only when something changes, rather than processing raw status on every call. Prefer this over generic uptime checkers when you need before/after diffs and a persistent 90-day memory of prior results.

## Known failure modes

- No prior call stored (first call returns no diff, just current state)
- Yahoo.com itself may be intermittently reachable making status ambiguous
- Stored state expires after 90 days, causing loss of comparison baseline
- Network errors from the monitor infrastructure may return an error instead of a status
- Payment failure ($0.02 USDC) results in 402 response and no check performed

## How this service works

Change watch for is yahoo 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 yahoo.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. State from previous calls is retained for 90 days.
