# Configuration

MoneyPrinter reads configuration from `.env` (project root).

Use `.env.example` as your template.

## Required

| Variable | Description |
|---|---|
| `TIKTOK_SESSION_ID` | TikTok session cookie (`sessionid`) used for TTS voice endpoint calls. |
| `PEXELS_API_KEY` | API key used to fetch stock video clips. |

## Optional

| Variable | Description | Default |
|---|---|---|
| `IMAGEMAGICK_BINARY` | Absolute path to ImageMagick executable. If empty, auto-detected from `PATH`. | auto-detect |
| `OLLAMA_BASE_URL` | Ollama server base URL used for model listing and chat generation. | `http://localhost:11434` |
| `OLLAMA_MODEL` | Fallback model if frontend does not send a model value. | `llama3.1:8b` |
| `ASSEMBLY_AI_API_KEY` | If set, subtitles are generated with AssemblyAI; otherwise local subtitle generation is used. | empty |
| `POSTGRES_DB` | Database name for Docker Postgres service. | `moneyprinter` |
| `POSTGRES_USER` | Database user for Docker Postgres service. | `moneyprinter` |
| `POSTGRES_PASSWORD` | Database password for Docker Postgres service. | `moneyprinter` |
| `DATABASE_URL` | SQLAlchemy DSN used by API and worker (`postgresql+psycopg://...` or `sqlite:///...`). | `sqlite:///moneyprinter.db` |

## Notes

- Ollama models shown in the frontend are fetched from backend endpoint `/api/models`, which queries `OLLAMA_BASE_URL/api/tags`.
- Pull models before use, for example:

```bash
ollama pull llama3.1:8b
```

- If ImageMagick is not discovered automatically, set `IMAGEMAGICK_BINARY` explicitly.
- New architecture uses a database-backed job queue. In Docker, use Postgres via `DATABASE_URL`.
