+## API Pattern
+
+Demio uses a straightforward REST API:
+- All requests require both `Api-Key` and `Api-Secret` headers
+- Responses are JSON objects
+- Registration returns a `join_link` URL for the attendee
+- Events have multiple "dates" (sessions), each with a unique `date_id`
+
+## Key Metrics
+
+### Event Metrics
+- `id` - Event ID
+- `name` - Event name
+- `date_id` - Session/date identifier
+- `status` - Event status (upcoming, past, active)
+- `type` - Event type (live, automated, on-demand)
+- `registration_url` - Public registration page URL
+
+### Participant Metrics
+- `name` - Participant name
+- `email` - Participant email
+- `status` - Attendance status (registered, attended, missed)
+- `attended_minutes` - Duration of attendance
+- `join_link` - Unique join URL for the participant
+
+## Parameters
