Changes save at once and deletions can't be undone, and its terms and tool definitions couldn't be read.\n\n**Aurinko Calendar API.** A public OpenAPI 3.0 spec covers 154 operations, with free/busy, meeting-time suggestion and booking profiles alongside calendar reads and writes, and prices start at $1 an active account a month. No status page, SLA, changelog or official SDK was found, and the application's client secret reaches every connected account.\n\n## Before you call either\n\n### Agenda Hero\n\n1. Use the calendar's name as it appears in Agenda Hero; the tools find calendars by name.\n2. Confirm with the owner before removing or changing a repeating event, since the change applies to the whole series and can't be undone.\n3. Don't try to edit events that come from a source calendar. They're read-only here and must be changed where they live.\n4. Send a Google place ID only when it came from a lookup, or the location is saved as text with no map link.\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## Questions\n\n### Which is better for AI agents, Agenda Hero or Aurinko Calendar API?\n\nAurinko Calendar API scores 45.6 (E) on agent readiness against Agenda Hero's 34.5 (F), and leads in 5 of 7 scored categories.
