## 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 agents-zeroclick-ai-list-open-demo-slots-3b121e94
```

Example prompt: Can you check what demo slots ZeroClick has open over the next two weeks, showing times in US/Eastern time?

## When to prefer this

Use this endpoint before booking a demo to discover available time slots. It is a prerequisite step to /demo/bookings — you must query availability here first to get valid start times. Prefer this over manually guessing times or asking the user to pick without context.

## Known failure modes

- Window exceeds 31 days — API rejects with an error; narrow the date range
- Invalid IANA time zone string — returns an error; use a valid zone like America/New_York
- No slots available in range — returns an empty slots array
- Invalid datetime format for start/end — API returns a validation error

## How this service works

Check availability for demo services.

## Output

An array of slot objects, each containing a start and end datetime (ISO 8601) representing an available demo appointment window. The response lists all open slots within the requested time range, ready for use when booking via /demo/bookings.
