## Which one, for what

### Apiroc Unified Calendar API (E)

Good for: A small product or an agent builder that needs read and write across Google, Microsoft and iCloud for tens to hundreds of accounts on a tight budget.

Ahead on:
- Agent ergonomics, 52 against 43
- Payments & pricing, 40 against 25
- Maintenance & community, 62 against 28

Also in its favour:
- Free to start without a card

Watch for: No status page history, changelog, OpenAPI spec, llms.txt or security.txt

### 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 35
- Schema & documentation, 61 against 44
- Security & auth, 54 against 21
- Transparency & trust, 69 against 50

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

**Apiroc Unified Calendar API.** $0.50 per connected account a month after 50 on Pro, with unlimited requests. No status page history, changelog, OpenAPI spec, llms.txt or security.txt.

**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

### Apiroc Unified Calendar API

1. Send the key in the `x-api-key` header from a server, never a browser
2. Call api.apiroc.com, since the SDK's old default host was api.onecalunified.com
3. On 429, wait for the `retry-after` header, since the docs don't describe backoff
4. Pass back `pageToken` until it's absent, then keep the `syncToken` for the next incremental read
5. Dedupe webhooks on `svix-id`, since Svix retries deliveries

### 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
