This workflow analyzes the **NASA Astronomy Picture of the Day (APOD)** and uses **AI Vision** to curate a matching **Spotify** track, creating a daily cosmic soundtrack.\n\n### How it works\n1. **Daily Trigger**: Runs every night at 10 PM.\n2. **Mood Logic**: Checks the day of the week (e.g., energetic Fridays, calm Mondays).\n3. **Visual Analysis**: OpenAI Vision analyzes the NASA image and the day's mood to generate audio parameters (Energy, Valence).\n4. **Curation**: Spotify finds a track matching these parameters.\n5. **Creative Writing**: OpenAI writes a short poem/caption linking the image and song.\n6. **Notification**: Posts the image, song, and poem to **Slack**.\n7. **Archive**: Saves the track to a specific Spotify playlist.\n\n### Requirements\n- **NASA API Key** (Free)\n- **OpenAI API Key** (GPT-4o supported)\n- **Spotify App Credentials** (Client ID/Secret)\n- **Slack Bot Token**\n\n### Setup\n- Create a Spotify Playlist and paste the ID into the **Save to Playlist** node.\n- Add your Slack Channel ID to the **Post to Slack** node."
