# Song Generation

Generate complete songs with vocals and full instrumental production using [each::sense](https://docs.eachlabs.ai/sense/overview) — the intelligent AI agent that automatically selects the best model for your request.

## Quick Start

> Requires an each::labs API key. Get one at [eachlabs.ai](https://eachlabs.ai).

### Using curl

```bash
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "messages": [{"role": "user", "content": "Generate an upbeat indie pop song about road trips and summer freedom, female vocal, 120 BPM, with acoustic guitar, claps, and a catchy whistling hook in the chorus"}],
    "stream": false
  }'
```

### Using Python (OpenAI SDK)

```python
from openai import OpenAI

client = OpenAI(
    api_key="YOUR_EACHLABS_API_KEY",
    base_url="https://eachsense-agent.core.eachlabs.run/v1"
)

response = client.chat.completions.create(
    model="eachsense/beta",
    messages=[{"role": "user", "content": "Generate an upbeat indie pop song about road trips and summer freedom, female vocal, 120 BPM, with acoustic guitar, claps, and a catchy whistling hook in the chorus"}]
)

print(response.choices[0].message.content)
```

### With Reference Image

```bash
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "messages": [{"role": "user", "content": [
              {"type": "text", "text": "Generate a song inspired by the mood and atmosphere of this image. Match the emotion, whether it feels melancholy, joyful, or mysterious."},
              {"type": "image_url", "image_url": {"url": "https://example.com/mood-photo.jpg"}}
            ]
          }
    ],
    "stream": false
  }'
```

> Images are sent inside messages using the OpenAI multimodal content format. Maximum 4 images per request.

### Streaming

Set `"stream": true` for real-time SSE responses, or `"stream": false` for complete result in a single response. Streaming is useful for showing progress in UIs; non-streaming is simpler for scripts and automation.

Walking down these empty streets at dawn
Shadows fading as the night moves on
Every step I take leads back to you
Underneath this sky of fading blue

We were golden, we were fire
Burning brighter, climbing higher
Now I'm standing in the rain
Chasing echoes of your name
```

## Common Pitfalls

- **No vocal direction** produces generic voices. Always specify gender, style, and energy level.
- **Missing tempo** lets the model guess BPM, which may not match your vision. Specify BPM.
- **Lyrics without structure markers** make it hard for the model to assign verses and choruses correctly.
- **Too many genre mixes** (e.g., "jazz-metal-country-electronic fusion") dilute the output. Blend 2 genres maximum.
- **Ignoring song length** may produce clips that are too short or too long for your needs.
