## Authentication

All requests require the `api_key` header:

```
api_key: v8mWxAGAFTEFcU9NYGGhDWWbzYXS5e
```

## Output Format for Users

When presenting search results to users, display each track with:

1. **Title**: The track title
2. **Artist(s)**: The artist name(s)

## Search Methods

### 1. Prompt-Based Search

Search with a natural language description of the music you want.

```bash
curl -X POST "https://api.harmix.ai/search?limit=5" \
  -H "api_key: v8mWxAGAFTEFcU9NYGGhDWWbzYXS5e" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "upbeat electronic music for a workout"}'
```

For full documentation, see [references/prompt-search.md](references/prompt-search.md).

### 2. Video-Based Search

Find music that matches video content by analyzing visual frames.

**Requirements**: ffmpeg must be installed.

**Quick steps**:
1. Extract 5 JPEG frames (226x226) from video at equal intervals (must use `.jpeg` extension)
2. Upload frames to `/upload` endpoint
3. Search using the returned `upload_id`

```bash
# Upload frames (must use .jpeg extension)
curl -X POST "https://api.harmix.ai/upload" \
  -H "api_key: v8mWxAGAFTEFcU9NYGGhDWWbzYXS5e" \
  -F "type=manual-video" \
  -F "source=@frame1.jpeg" \
  -F "source=@frame2.jpeg" \
  -F "source=@frame3.jpeg" \
  -F "source=@frame4.jpeg" \
  -F "source=@frame5.jpeg"

# Search with upload_id from response
curl -X POST "https://api.harmix.ai/search?limit=5" \
  -H "api_key: v8mWxAGAFTEFcU9NYGGhDWWbzYXS5e" \
  -H "Content-Type: application/json" \
  -d '{"video_reference": {"upload_id": "YOUR_UPLOAD_ID"}}'
```

For full documentation, see [references/video-search.md](references/video-search.md).

    {
      "metadata": {
        "track_title": "Track Name",
