# MiniMax Music 3 API

> Lagu penuh dengan vokal daripada lirik dan penerangan gaya anda, sehingga 5 minit.

MiniMax Music 3 menyanyikan lirik anda dengan susunan lengkap. Terangkan genre, tempo, nada, suasana, vokal dan instrumen dalam prompt, dan tandakan struktur lagu dalam lirik dengan tag seperti [verse], [chorus] dan [bridge], setiap satunya pada baris sendiri. Tempoh (1 hingga 300 saat, 60 secara lalai) ialah had atas; lagu mungkin berakhir lebih awal.

- Model id: `minimax/music-3`
- Made by: MiniMax
- Category: Text to Music
- Output: audio
- Price: $0.002 / second (60 s ≈ $0.12) (cheapest run $0.12 (120 API credits))
- Run: `POST https://api.doitong.com/v1/run/minimax/music-3`
- Quote: `POST https://api.doitong.com/v1/quote/minimax/music-3`
- Docs page: https://doitong.com/ms/developers/models/minimax/music-3

## Pricing

Price: **$0.002 / second (60 s ≈ $0.12)**. Billed per second of output (`duration`, default 60).

The full example input below costs $0.06 = 60 API credits (30 s × 2 API credits).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/minimax/music-3` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Run it

Set `DOITONG_API_KEY` to a key from https://doitong.com/developers/dashboard#keys. `?wait=20` returns the finished request in the same call when it is ready within 20 seconds; otherwise poll `GET /requests/{id}` (it also accepts `?wait=`), or pass `webhook_url`.

### curl

```bash
# Run the model; wait up to 20 s for the finished result in the same call
curl -X POST "https://api.doitong.com/v1/run/minimax/music-3?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Genre: acoustic pop. BPM: 96. Key: C major. Warm and intimate, soft female vocal, guitar and light piano",
    "lyrics": "[verse]\nMorning light filtering through the pine\nEvery quiet street is yours and mine\n[chorus]\nSoftly the world begins to breathe",
    "duration": 30
  }'

# Still "queued" or "running"? Poll with the id from the response:

### MCP

The MCP server at `https://api.doitong.com/v1/mcp` exposes the tools `search_models`, `get_model`, `quote`, `run`, `get_request`, `cancel_request`, `list_requests`, `create_upload` and `get_account`. A `run` call for this model:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "run",
    "arguments": {
      "model_id": "minimax/music-3",
      "input": {
        "prompt": "Genre: acoustic pop. BPM: 96. Key: C major. Warm and intimate, soft female vocal, guitar and light piano",
        "lyrics": "[verse]\nMorning light filtering through the pine\nEvery quiet street is yours and mine\n[chorus]\nSoftly the world begins to breathe",
        "duration": 30
      },
      "wait_seconds": 20
    }
  }
}
```

## Response

Every call returns a request object. `status` is one of `queued`, `running`, `succeeded`, `failed`, `canceled`. `outputs` lists the generated files with URLs on our storage (kept forever, or 7 days with `?storage=temporary`; `storage` says which); `output` is the model's own result object with the same URLs.
