## 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 coinbase-com-downtime-change-watch-06a854cf
```

Example prompt: Check if coinbase.com is down right now and let me know if anything has changed since the last time you checked — I want to see what fields flipped and when it was last seen in that state.

## When to prefer this

Choose this endpoint when you need change-aware monitoring of coinbase.com specifically — not just a point-in-time ping, but a stateful comparison that tells you whether anything has actually changed since the last check. Ideal for scheduled agent workflows that should trigger on state transitions (down→up or up→down) rather than polling raw status on every call.

## Known failure modes

- If coinbase.com check itself times out, the status may be inconclusive
- First call for a given query has no previous result to compare against, so 'changed' may be null or false by default
- Results older than 90 days are purged, resetting the comparison baseline
- Payment failure (insufficient USDC) will prevent the check from running
- Network issues between the monitor and coinbase.com may cause false positives

## How this service works

Change watch for is coinbase 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 coinbase.com, a boolean 'changed' flag indicating whether the result differs from the previous call, an object listing each field that changed with its before and after values, and a timestamp of when the status was last observed. Previous results are retained for 90 days per query.
