# MiniMax Music 3 API

> 가사와 스타일 설명으로 보컬이 포함된 최대 5분 길이의 완성곡을 생성합니다.

MiniMax Music 3는 완성된 편곡에 가사를 얹어 노래합니다. 프롬프트에 장르, 템포, 조성, 분위기, 보컬 및 악기를 설명하고, [verse], [chorus], [bridge] 같은 태그를 사용해 가사에 곡 구조를 표시하세요. 각 태그는 자체 줄에 작성해야 합니다. 지속 시간(1~300초, 기본값 60)은 상한이며 곡이 더 일찍 끝날 수 있습니다.

- 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/ko/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 |  |  | 정밀한 제어를 위해 Structured Caption을 사용할 수 있는 음악 생성 프롬프트입니다. 섹션별 편곡 및 보컬 세부 정보와 장르, BPM, 키, 감정 진행을 지정하는 전역 메타데이터를 결합합니다. 일반 설명에는 원하는 스타일과 분위기, 보컬과 악기 사용 방식, 편곡을 포함합니다. |
| `lyrics` |  | string | yes |  |  | 부를 가사입니다. 앞에 구조 태그가 있는 줄에 함께 작성된 단어는 모델 입력 계약에 따라 삭제됩니다. [intro], [verse], [pre-chorus], [chorus], [post-chorus], [bridge], [instrumental], [solo], [outro]를 포함한 각 태그를 별도 줄에 작성하세요. |
| `duration` |  | number | no | `60` | 1 – 300 | 출력 길이를 보장하지 않는 오디오 길이 제한이며, 초 단위로 측정됩니다. 응답에는 실제 길이가 보고되며, 생성이 일찍 중단되면 더 짧을 수 있습니다. |
| `seed` |  | integer \| null | no |  |  | 재현 가능한 생성을 위한 시드입니다. 값을 제공하지 않으면 무작위로 선택됩니다. |
| `num_inference_steps` |  | integer | no | `30` | 1 – 100 | 각 8초 디노이징 청크의 플로 매칭을 위한 Euler 단계 수입니다. |
| `guidance_scale` |  | number | no | `1.7` | 0 – 20 | 플로 매칭 중 분류기 없는 가이던스 강도입니다. |

## Example input

Required parameters only:

```json
{
  "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"

A fuller example:

```json
{
  "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",

```

## 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"
```

### JavaScript

### 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",

    "duration": 30,
}

# 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
while request["status"] in ("queued", "running"):
    request = requests.get(API + "/requests/" + request["id"], params={"wait": 20}, headers=headers).json()
if request["status"] != "succeeded":
    raise RuntimeError(request["error"])
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.

### Output fields (`output`)

| Field | Type | Description |

| `seed` | integer | 생성에 사용된 무작위 시드입니다. |
| `duration` | number | 실제로 생성된 오디오의 초 수를 보고합니다. 요청한 길이와 반드시 같지는 않습니다. |
