No external API keys required for basic functionality. Optional Discord integration available for future features.

The system uses SQLite with the following schema:

-- Events table
CREATE TABLE events_N (
  id INTEGER PRIMARY KEY AUTOINCREMENT,
  name TEXT NOT NULL,
  password_hash TEXT NOT NULL,
  location TEXT,
  created_at DATETIME DEFAULT CURRENT_TIMESTAMP
);

-- Attendees table  
CREATE TABLE attendees_N (
  id INTEGER PRIMARY KEY AUTOINCREMENT,
  event_id INTEGER NOT NULL,
  name TEXT NOT NULL,
  external_id TEXT,
  FOREIGN KEY (event_id) REFERENCES events_2(id)
);

-- Check-ins table
CREATE TABLE checkins_N (
  id INTEGER PRIMARY KEY AUTOINCREMENT,
  event_id INTEGER NOT NULL,
  attendee_id INTEGER NOT NULL,
  checked_in_at DATETIME DEFAULT CURRENT_TIMESTAMP,
  FOREIGN KEY (event_id) REFERENCES events_2(id),
  FOREIGN KEY (attendee_id) REFERENCES attendees_1(id)
);
