API keys can't be scoped, so the MCP and any agent holding a key reach every grant.\n\n**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.\n\n## Before you call either\n\n### Nylas Calendar and Scheduler API\n\n1. Address calendar calls to /v3/grants/\u003cgrant_id\u003e, one grant per connected account\n2. List events in the window before retrying a create, since event writes have no idempotency key\n3. Point the MCP client at mcp.eu.nylas.com if the application lives in the EU region\n4. On 429, use the passed-through `Retry-After` if present, otherwise back off per grant\n5. Mint a short-lived API key for the agent with `expires_in` rather than sharing the main one\n\n### Zoom Scheduler API\n\n1. Call `GET /scheduler/schedules/{scheduleId}/available_times` and book only a spot whose status is `available`\n2. Send `start_date_time` in ISO 8601 with the booker's IANA `time_zone` to `POST /scheduler/attendee`. Expect 409 on a conflict\n3. To move a booking, cancel it with `PATCH /scheduler/events/{eventId}` and `status` set to `cancelled`, then book the new slot\n4. List scheduled events before retrying a booking, because no idempotency key is documented\n5. Request a new Server-to-Server OAuth token every hour. That grant issues no refresh token\n\n## Questions\n\n### Which is better for AI agents, Nylas Calendar and Scheduler API or Zoom Scheduler API?\n\nNylas Calendar and Scheduler API scores 71 (BB) on agent readiness against Zoom Scheduler API's 50.6 (D), and leads in every scored category.\n\n### Do Nylas Calendar and Scheduler API and Zoom Scheduler API need an API key?\n\nNylas Calendar and Scheduler API takes an API key or an OAuth sign-in. Zoom Scheduler API uses an OAuth sign-in.\n\n### Can an agent call Nylas Calendar and Scheduler API and Zoom Scheduler API without installing anything?\n\nYes. Nylas Calendar and Scheduler API has a hosted endpoint at https://api.us.nylas.com/v3 and Zoom Scheduler API at https://api.zoom.us/v2.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/nylas-calendar-vs-zoom-scheduler.json, and with the fewest tokens: https://www.anchorterminal.com/compare/nylas-calendar-vs-zoom-scheduler.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"nylas-calendar\", \"b\": \"zoom-scheduler\"}`.
