## 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 calendly-domain-verification-change-watch-d6360a9e
```

Example prompt: Keep an eye on whether acme.com has a valid Calendly domain verification DNS record and let me know as soon as that status changes compared to the last time you checked.

## When to prefer this

Use this endpoint when you need to detect changes in Calendly domain verification status over time rather than just a point-in-time lookup. It is ideal for scheduling periodic checks or building alerting workflows where you want to know the diff between the current and previous state without managing your own state storage. The 90-day comparison window makes it suitable for infrequent polling scenarios.

## Known failure modes

- Domain not found or invalid domain name returns an error
- No previous check stored (first call returns no diff, only current state)
- DNS lookup timeout or upstream resolver failure
- Payment of $0.02 USDC not processed, request rejected
- Domain verification record temporarily unavailable due to DNS propagation delays

## How this service works

Change watch for has calendly domain verification: runs the check, compares it with the result from your previous call for the same domain (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 Calendly domain verification status, a boolean indicating whether it changed since the last check, the specific fields that changed with before and after values, and the timestamp of when the state was last observed. Historical state is retained for 90 days for comparison.
