# Jackbox Game Picker API

## Overview

The API manages Jackbox Party Pack games, runs gaming sessions, tracks popularity via voting, picks games with weighted random selection, and notifies external systems via webhooks and WebSocket.

## Base URL

| Environment | Base URL | Notes |
|-------------|----------|-------|
| Local development | `http://localhost:5000` | Backend direct |
| Docker Compose | `http://localhost:3000/api` | Via Vite/Nginx proxy |

All REST endpoints are prefixed with `/api/` except `/health`.

## Authentication

1. **Login**: POST to `/api/auth/login` with JSON body:

   ```json
   { "key": "<admin-key>" }
   ```

   Returns a JWT token.

2. **Authorization**: Include the token in requests:
   ```
   Authorization: Bearer <token>
   ```

3. **Expiry**: Tokens expire in 24 hours.

### Public Endpoints (no auth required)

- `GET /api/games`
- `GET /api/games/packs`
- `GET /api/games/meta/packs`
- `GET /api/games/{id}`
- `GET /api/sessions`
- `GET /api/sessions/active`
- `GET /api/sessions/{id}`
- `GET /api/sessions/{id}/games`
- `GET /api/sessions/{id}/votes`
- `GET /api/sessions/{sessionId}/games/{sessionGameId}/status-live`
- `GET /api/votes`
- `GET /api/stats`
- `POST /api/pick`
- `GET /health`

All write and admin operations require authentication.

## Request/Response Format

- Request and response bodies use JSON. Set `Content-Type: application/json`.
- **Exceptions**:
  - `GET /api/games/export/csv` returns `text/csv`
  - `GET /api/sessions/{id}/export` returns `text/plain` or `application/json` depending on `format` query param

## Error Handling

All errors return:

```json
{ "error": "description" }
```

| Status | Meaning |
|--------|---------|
| 400 | Bad request / validation failure |
| 401 | No token provided |
| 403 | Invalid or expired token |
| 404 | Not found |
| 409 | Conflict (e.g. duplicate vote) |
| 500 | Server error |

Global error handler may include additional detail:

```json
{ "error": "Something went wrong!", "message": "<details>" }
```

## Boolean Fields

SQLite stores booleans as integers (0/1). In request bodies, pass JavaScript booleans (`true`/`false`); the API converts them. In responses, expect `0`/`1` for game and session fields. **Exception**: `Webhook.enabled` returns a JavaScript boolean.

## Pagination

Most list endpoints return full result sets. The exception is `GET /api/votes`, which supports pagination via `page` and `limit` query parameters (default: page 1, limit 50, max 100).
