# Elevenlabs Music API

> 프롬프트 또는 구조화된 작곡 계획으로 구동되는 텍스트-음악 생성기로 반주 전용 옵션을 지원

최대 4100자의 텍스트 `prompt` 또는 상세한 `composition_plan`에서 음악을 작곡합니다. 프롬프트 사용 시 `music_length_ms`는 3000~600000밀리초이며, `force_instrumental`로 보컬을 확실히 제외할 수 있습니다. `respect_sections_durations`는 계획된 섹션의 시간을 얼마나 엄격하게 따를지 결정합니다. `output_format`으로 다양한 코덱과 샘플 레이트를 선택할 수 있습니다.

- Model id: `elevenlabs/music`
- Made by: ElevenLabs
- Category: Text to Music
- Output: audio
- Price per minute of your output audio: $0.60 / minute of output audio (cheapest run $0.60 (600 API credits))
- Run: `POST https://api.doitong.com/v1/run/elevenlabs/music`
- Quote: `POST https://api.doitong.com/v1/quote/elevenlabs/music`
- Docs page: https://doitong.com/ko/developers/models/elevenlabs/music

## Pricing

Price: **$0.60 / minute of output audio**. Price per minute of your output audio: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

The full example input below costs $1.80 = 1800 API credits (3 min output audio × $0.60).

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/elevenlabs/music` 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 \| null | no |  | ≤ 4100 characters | 원하는 음악에 대한 텍스트 설명입니다. |
| `composition_plan` |  | object {positive_global_styles, negative_global_styles, sections} \| null | no |  |  | 음악의 구성을 정의하는 계획입니다. |
| `composition_plan.positive_global_styles` |  | array of string | yes |  |  | 노래 전체에 포함할 스타일입니다. |
| `composition_plan.negative_global_styles` |  | array of string | yes |  |  | 노래 전체에서 제외할 스타일입니다. |
| `composition_plan.sections` |  | array of object {section_name, positive_local_styles, negative_local_styles, duration_ms, lines} | yes |  |  | 노래를 구성하는 섹션입니다. |
| `composition_plan.sections[].section_name` |  | string | yes |  | 1 – 100 characters | 섹션 이름이며, 길이는 1~100자입니다. |
| `composition_plan.sections[].positive_local_styles` |  | array of string | yes |  |  | 이 섹션에 포함할 스타일입니다. |
| `composition_plan.sections[].negative_local_styles` |  | array of string | yes |  |  | 이 섹션에서 제외할 스타일입니다. |
| `composition_plan.sections[].duration_ms` |  | integer | yes |  | 3,000 – 120,000 | 섹션 길이(밀리초)이며, 3000 ms~120000 ms 범위입니다. |
| `composition_plan.sections[].lines` |  | array of string | yes |  |  | 이 섹션의 가사이며, 한 줄당 200자로 제한됩니다. |
| `music_length_ms` |  | integer \| null | no |  | 3,000 – 600,000 | 선택적 노래 길이(밀리초)이며, 3000 ms~600000 ms 범위입니다. 프롬프트를 사용할 때만 적용됩니다. 생략하면 모델이 프롬프트에서 길이를 결정합니다. |
| `force_instrumental` |  | boolean | no | `false` |  | 프롬프트 사용 시에만 사용할 수 있는 연주곡 전용 제어입니다. true로 설정하면 연주곡 출력이 보장되고, false로 설정하면 프롬프트에 따라 연주곡 또는 보컬 음악이 생성됩니다. |
| `respect_sections_durations` |  | boolean | no | `true` |  | `composition_plan`의 섹션 타이밍 적용 여부입니다. 해당 계획 외부에서는 효과가 없습니다. False는 모델이 개별 섹션 길이를 변경하도록 허용하여 계획의 전체 노래 길이는 바꾸지 않고 일반적으로 품질과 지연 시간을 개선합니다. true는 각 섹션의 `duration_ms`를 정확히 적용합니다. |
| `output_format` |  | enum (string) | no | `mp3_44100_128` | `mp3_22050_32`, `mp3_44100_32`, `mp3_44100_64`, `mp3_44100_96`, `mp3_44100_128`, `mp3_44100_192`, `pcm_8000`, `pcm_16000`, `pcm_22050`, `pcm_24000`, `pcm_44100`, `pcm_48000`, `ulaw_8000`, `alaw_8000`, `opus_48000_32`, `opus_48000_64`, `opus_48000_96`, `opus_48000_128`, `opus_48000_192` | 등급 요구 사항이 적용되는 오디오 출력 형식입니다. 192 kbps MP3는 Creator 등급 이상이 필요하고, 44.1 kHz PCM은 Pro 등급 이상이 필요합니다. 값은 `codec_sample_rate_bitrate` 형식을 따릅니다. 예를 들어 `mp3_22050_32`는 22.05 kHz MP3와 32 kbs 비트레이트를 지정합니다. Twilio 오디오 입력에는 μ-law가 일반적으로 사용되며, mu-law로 표기하거나 u-law로 근사해 표기하기도 합니다. |

## Example input

Required parameters only:

```json
{}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## 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/elevenlabs/music?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

# 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

```javascript
const API = "https://api.doitong.com/v1";
const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/elevenlabs/music?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

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

payload = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/elevenlabs/music", 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": "elevenlabs/music",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.
