# Trello.com Downtime Change Watcher

> Trello.com Downtime Change Watcher is a paid API for AI agents from monitor.intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-28).

## 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 trello-com-downtime-change-watcher-d0ae2532
```

Example prompt: Run the Trello.com down-check watcher and tell me if its status has changed since the last time we checked — I want to know the current state, whether it flipped, and what exactly changed.

## When to prefer this

Use this endpoint when you specifically need change detection for Trello.com — not just a one-off status check, but a stateful comparison against your last query. Ideal for scheduled polling agents that need to trigger actions only when status flips (down→up or up→down) rather than on every check. Better than a generic ping if you need structured diff output with before/after field values.

## Known failure modes

- No previous check stored (first call returns current status with no diff)
- Previous result older than 90 days (treated as first call, no comparison available)
- Network timeout reaching Trello.com (may return error or indeterminate status)
- Payment failure — $0.02 USDC per call required via x402 protocol

## How this service works

Change watch for is trello 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 Trello.com, a boolean 'changed' flag indicating whether status differs from the previous call, a list of fields that changed with before/after values, and a timestamp of when the status was last seen. Previous result is retained for 90 days.
