## Output

Returns a record keyed by date. Each value is an array of slot objects.

| Field            | Type      | Required | Description                                     |
| ---------------- | --------- | -------- | ----------------------------------------------- |
| `start`          | `string`  | Yes      | Slot start.                                     |
| `end`            | `string`  | No       | Slot end when `format` is `"range"`.            |
| `bookingUid`     | `string`  | No       | Booking identifier for a partially seated slot. |
| `seatsBooked`    | `integer` | No       | Seats already booked for a seated event.        |
| `seatsRemaining` | `integer` | No       | Seats still available for a seated event.       |
| `seatsTotal`     | `integer` | No       | Total seats for a seated event.                 |

Identify an event with `eventTypeId`, or use the slug and owner fields for a personal, team, organization, or dynamic event. The action sends multiple `usernames` as a comma-separated Cal.com filter.

Cal.com enforces account role, plan, and availability requirements. Provider rejections surface as structured action failures with the HTTP status and any `Retry-After` delay.
