No status page, SLA, changelog or official SDK was found, and the application's client secret reaches every connected account.\n\n**Cozi Family Organizer.** Documented read-only calendar exchange. No official external-agent write API verified.\n\n## Before you call either\n\n### Aurinko Calendar API\n\n1. Use `https://api.aurinko.io/v1`. Several cURL examples in the docs print `https:/api.aurinko.io` with one slash\n2. Send `If-Match` with the event's `etag` on `PATCH /v1/calendars/{calendarId}/events/{eventId}`. A stale value returns 412\n3. Use `primary` as the calendar ID for an account's main calendar, and page with `pageToken` until none is returned\n4. Hold a slot with `reserveForMinutes` on the booking `meeting` call, then confirm or cancel the reservation, since no idempotency key exists\n5. Retry 429, 408 and 5xx with exponential backoff. Do not retry 404. A 429 can come from Google or Microsoft limits behind the API\n\n### Cozi Family Organizer\n\n1. Use official read-only feeds for calendar visibility.\n2. Make edits in the originating calendar and allow for the refresh delay.\n\n## Questions\n\n### Which is better for AI agents, Aurinko Calendar API or Cozi Family Organizer?\n\nAurinko Calendar API scores 45.6 (E) on agent readiness against Cozi Family Organizer's 15.7 (F), and leads in every scored category.\n\n### Can an agent call Aurinko Calendar API and Cozi Family Organizer without installing anything?\n\nAurinko Calendar API has a hosted endpoint at https://api.aurinko.io.
