# MiniMax Music 3 API

> Amhráin iomlána le guth ó do liricí agus cur síos stíle, suas le 5 nóiméad.

Canann MiniMax Music 3 do liricí thar eagar iomlán. Déan cur síos ar an seánra, ar an luas, ar an eochair, ar an meon, ar na guthanna agus ar na huirlisí sa phrompt, agus marcáil struchtúr an amhráin sna liricí le clibeanna amhail [verse], [chorus] agus [bridge], gach ceann ar a líne féin. Is teorainn uachtarach é an fad (1 go 300 soicind, 60 de réir réamhshocraithe); féadfaidh an t-amhrán críochnú níos luaithe.

- 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`

## 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.

Clúdaíonn tuairisc ghinearálta an stíl agus an giúmar inmhianaithe, an chaoi a n-úsáidtear guthanna agus uirlisí, agus an socrú. |
| `lyrics` |  | string | yes |  |  | Liricí le canadh; caitear amach aon fhocail atá ar an líne chéanna le clib struchtúir tosaigh faoi chonradh ionchuir na samhla. Coinnigh gach clib ar líne ar leith, lena n-áirítear [intro], [verse], [pre-chorus], [chorus], [post-chorus], [bridge], [instrumental], [solo] agus [outro]. |
| `duration` |  | number | no | `60` | 1 – 300 | Teorainn fhad na fuaime, tomhaiste i soicindí, seachas fad aschuir ráthaithe. Tuairiscíonn an freagra an fad iarbhír, a d’fhéadfadh a bheith níos giorra má stopann an ghiniúint go luath. |
| `seed` |  | integer \| null | no |  |  | Síol le haghaidh giniúint in-atáirgthe, roghnaithe go randamach mura soláthraíonn tú luach. |
| `num_inference_steps` |  | integer | no | `30` | 1 – 100 | Comhaireamh céimeanna Euler le haghaidh meaitseáil sreafa laistigh de gach smután dínóisiúlaithe 8 soicind. |
| `guidance_scale` |  | number | no | `1.7` | 0 – 20 | Neart treorach saor ó aicmitheoir le linn meaitseáil sreafa. |

## 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" \

### 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 |
|---|---|---|
| `audio` | object {url, content_type, file_name, file_size} | Comhad fuaime aschuir i bhformáid WAV steirió, ag úsáid 44.1 kHz agus samplaí 16-giotán. |
| `seed` | integer | Síol randamach a úsáidtear le linn giniúna. |
| `duration` | number | Tuairiscíonn sé cé mhéad soicind fuaime a gineadh i ndáiríre, rud nach gá a bheith chomh fada leis an méid a iarradh. |
