## Which one, for what

### Cozi Family Organizer (F)

Good for: Cozi is a shared family calendar, shopping-list and meal-planning app.

Ahead on:
- Payments & pricing, 30 against 25

Watch for: No official external-agent write API verified

### Zoom Scheduler API (D)

Good for: An agent booking into a Zoom Scheduler user's or team's booking pages, with slot lookup, booking, cancellation and two webhooks.

Ahead on:
- Reliability, 63 against 15
- Schema & documentation, 61 against 15
- Agent ergonomics, 43 against 10
- Security & auth, 54 against 10
- Maintenance & community, 28 against 0
- Transparency & trust, 69 against 36

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: Zoom's API terms (section 3.7.9) forbid using the APIs to monitor availability or performance, or for benchmarking. This matters before any probe is run

## Verdicts

**Cozi Family Organizer.** Documented read-only calendar exchange. No official external-agent write API verified.

**Zoom Scheduler API.** Each of the 24 operations has its own granular OAuth scope, and Zoom Scheduler and the REST API are separate components on the status page. No operation moves a booking, no official SDK covers Scheduler, and Zoom's API terms forbid benchmarking or monitoring the service.

## Before you call either

### Cozi Family Organizer

1. Use official read-only feeds for calendar visibility.
2. Make edits in the originating calendar and allow for the refresh delay.

### Zoom Scheduler API

1. Call `GET /scheduler/schedules/{scheduleId}/available_times` and book only a spot whose status is `available`
2. Send `start_date_time` in ISO 8601 with the booker's IANA `time_zone` to `POST /scheduler/attendee`. Expect 409 on a conflict
3. To move a booking, cancel it with `PATCH /scheduler/events/{eventId}` and `status` set to `cancelled`, then book the new slot
4. List scheduled events before retrying a booking, because no idempotency key is documented
5. Request a new Server-to-Server OAuth token every hour. That grant issues no refresh token
