# MiniMax Music 3 API

> Fullständiga låtar med sång från dina texter och en stilbeskrivning, upp till 5 minuter.

MiniMax Music 3 sjunger dina texter över ett komplett arrangemang. Beskriv genre, tempo, tonart, stämning, sång och instrument i prompten och markera låtstrukturen i texten med taggar som [verse], [chorus] och [bridge], en på varje rad. Längden (1 till 300 sekunder, 60 som standard) är en övre gräns; låten kan sluta tidigare.

- 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.ru/v1/run/minimax/music-3`
- Quote: `POST https://api.doitong.ru/v1/quote/minimax/music-3`
- Docs page: https://doitong.com/sv/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.ru/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 för musikgenerering som kan använda en Structured Caption för exakt styrning: kombinera sektionsspecifik arrangering och sångdetaljer med globala metadata som anger genre, BPM, tonart och emotionell utveckling. En allmän beskrivning omfattar önskad stil och stämning, hur sång och instrument används samt arrangemanget. |
| `lyrics` |  | string | yes |  |  | Text som ska sjungas; ord som delar rad med en inledande strukturtagg kasseras enligt modellens indatakontrakt. Håll varje tagg på en separat rad, inklusive [intro], [verse], [pre-chorus], [chorus], [post-chorus], [bridge], [instrumental], [solo] och [outro]. |
| `duration` |  | number | no | `60` | 1 – 300 | Gräns för ljudlängd, mätt i sekunder, snarare än en garanterad utdata-längd. Svaret rapporterar den faktiska längden, som kan vara kortare om genereringen avslutas tidigt. |
| `seed` |  | integer \| null | no |  |  | Seed för reproducerbar generering, väljs slumpmässigt om du inte anger ett värde. |
| `num_inference_steps` |  | integer | no | `30` | 1 – 100 | Antal Euler-steg för flow matching inom varje brusreduceringsblock på 8 sekunder. |
| `guidance_scale` |  | number | no | `1.7` | 0 – 20 | Styrka för classifier-free guidance under flow matching. |

## 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",
  "duration": 30
}
```

## 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.ru/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.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

### Python

```python
import os
import requests

API = "https://api.doitong.ru/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",
    "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,
}

# 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.ru/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 |
|---|---|---|
| `audio` | object {url, content_type, file_name, file_size} | Utdatafil med ljud i stereo-WAV-format, med 44.1 kHz och 16-bitars samplingar. |
| `seed` | integer | Slumpmässigt seed som används under genereringen. |
| `duration` | number | Rapporterar hur många sekunder ljud som faktiskt genererades, vilket inte nödvändigtvis är lika långt som begärt. |
