## 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-delta-com-down-watch-3098ef9c
```

Example prompt: Keep an eye on delta.com for me and let me know if its availability status changes — I want to know the moment it goes down or comes back up.

## When to prefer this

Choose this endpoint when you need change detection rather than just a raw status check — it tells you not only whether delta.com is down but whether its state has shifted since your last poll. Ideal for scheduling periodic checks and triggering alerts only on transitions, avoiding redundant notifications when status is stable.

## Known failure modes

- No previous check result stored (first call returns no diff)
- delta.com may be intermittently slow causing false positives
- Stale comparison if more than 90 days since last call — prior result purged
- Network timeout reaching delta.com from edge
- Payment failure at $0.02 USDC per call blocks the check

## How this service works

Change watch for is delta 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 delta.com, a boolean 'changed' flag indicating whether the result differs from the previous call, a list of fields that changed with their before and after values, and the timestamp of when the status was last seen. Previous results are retained for up to 90 days per query.
