Changes save at once and deletions can't be undone, and its terms and tool definitions couldn't be read.\n\n**Cronofy API.** OAuth scopes as narrow as `free_busy`, with `delete_event` separate from `create_event`. Production pricing starts at $819 a month billed yearly.\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### Cronofy API\n\n1. Call the data centre host the account was created in (api-uk, api-de and so on), since data never crosses regions\n2. Reuse the same `event_id` when retrying an event write, since Cronofy upserts on it\n3. Ask for `response_format` slots when you want bookable times rather than free periods\n4. On 423, ask the user to relink, since Cronofy has already emailed them\n5. Keep under 50 requests a second and 500 a minute, and pause on 429\n\n## Questions\n\n### Which is better for AI agents, Agenda Hero or Cronofy API?\n\nCronofy API scores 64.2 (B) on agent readiness against Agenda Hero's 34.5 (F), and leads in 5 of 7 scored categories.\n\n### Can an agent call Agenda Hero and Cronofy API without installing anything?\n\nYes.
