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

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
