# MiniMax Music 3 API

> Lagu lengkap dengan vokal dari lirik dan deskripsi gaya Anda, hingga 5 menit.

MiniMax Music 3 menyanyikan lirik Anda dalam aransemen lengkap. Jelaskan genre, tempo, nada dasar, suasana, vokal, dan instrumen dalam prompt, lalu tandai struktur lagu dalam lirik dengan tag seperti [verse], [chorus], dan [bridge], masing-masing pada barisnya sendiri. Durasi (1 hingga 300 detik, default 60) adalah batas atas; lagu dapat 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/id/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.

## Input parameters

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  |  | Prompt pembuatan musik yang dapat menggunakan Structured Caption untuk kontrol presisi: gabungkan aransemen dan detail vokal spesifik bagian dengan metadata global yang menentukan genre, BPM, kunci, dan perkembangan emosi. Deskripsi umum mencakup gaya dan suasana yang diinginkan, penggunaan vokal dan instrumen, serta aransemennya. |
| `lyrics` |  | string | yes |  |  | Lirik yang akan dinyanyikan; kata apa pun yang berbagi baris dengan tag struktur pembuka akan dibuang sesuai kontrak input model. Pertahankan setiap tag pada baris terpisah, termasuk [intro], [verse], [pre-chorus], [chorus], [post-chorus], [bridge], [instrumental], [solo] dan [outro]. |
| `duration` |  | number | no | `60` | 1 – 300 | Batas durasi audio, diukur dalam detik, bukan panjang output yang dijamin. Respons melaporkan durasi aktual, yang dapat lebih pendek jika pembuatan berhenti lebih awal. |
| `seed` |  | integer \| null | no |  |  | Seed untuk pembuatan yang dapat direproduksi, dipilih secara acak kecuali Anda memberikan nilai. |
| `num_inference_steps` |  | integer | no | `30` | 1 – 100 | Jumlah langkah Euler untuk flow matching dalam setiap chunk denoising berdurasi 8 detik. |
| `guidance_scale` |  | number | no | `1.7` | 0 – 20 | Kekuatan classifier-free guidance selama flow matching. |

## 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:
curl "https://api.doitong.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"

### Python

```python
import os
import requests

API = "https://api.doitong.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "prompt": "Genre: acoustic pop. BPM: 96. Key: C major. Warm and intimate, soft female vocal, guitar and light piano",

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/minimax/music-3", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is

print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### 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.
