# Elevenlabs Music API

> 由提示或結構化作曲計畫驅動的文字轉音樂生成器，支援純樂器模式

從最多 4100 個字元的文字 `prompt`，或詳細的 `composition_plan` 創作音樂。使用提示詞時，`music_length_ms` 可介於 3000 至 600000 毫秒，`force_instrumental` 可保證不含人聲。`respect_sections_durations` 控制計畫區段計時的嚴格程度。透過 `output_format` 提供多種編碼器與取樣率選項。

- 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.ru/v1/run/elevenlabs/music`
- Quote: `POST https://api.doitong.ru/v1/quote/elevenlabs/music`
- Docs page: https://doitong.com/zh-TW/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.ru/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 | 所需音樂的文字描述。 |
| `composition_plan` |  | object {positive_global_styles, negative_global_styles, sections} \| null | no |  |  | 定義音樂組成的計畫。 |
| `composition_plan.positive_global_styles` |  | array of string | yes |  |  | 整首歌曲要包含的風格。 |
| `composition_plan.negative_global_styles` |  | array of string | yes |  |  | 整首歌曲要排除的風格。 |
| `composition_plan.sections` |  | array of object {section_name, positive_local_styles, negative_local_styles, duration_ms, lines} | yes |  |  | 組成歌曲的區段。 |
| `composition_plan.sections[].section_name` |  | string | yes |  | 1 – 100 characters | 區段名稱，長度為 1 至 100 個字元。 |
| `composition_plan.sections[].positive_local_styles` |  | array of string | yes |  |  | 此區段要包含的風格。 |
| `composition_plan.sections[].negative_local_styles` |  | array of string | yes |  |  | 此區段要排除的風格。 |
| `composition_plan.sections[].duration_ms` |  | integer | yes |  | 3,000 – 120,000 | 區段長度（以毫秒計），範圍為 3000 ms 至 120000 ms。 |
| `composition_plan.sections[].lines` |  | array of string | yes |  |  | 此區段的歌詞，每行最多 200 個字元。 |
| `music_length_ms` |  | integer \| null | no |  | 3,000 – 600,000 | 選用的歌曲時長（以毫秒計），範圍為 3000 ms 至 600000 ms，僅在使用提示詞時適用。省略時，模型會根據提示詞決定時長。 |
| `force_instrumental` |  | boolean | no | `false` |  | 僅器樂控制項，僅在使用提示詞時可用。設為 true 可保證輸出器樂；false 則依提示詞允許器樂或非器樂音樂。 |
| `respect_sections_durations` |  | boolean | no | `true` |  | `composition_plan` 的區段時長強制設定，對該計畫以外的內容無效。False 允許模型調整個別區段長度，通常可改善品質與延遲，且不改變歌曲總時長；true 則強制每個區段嚴格使用其 `duration_ms`。 |
| `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` | 音訊輸出格式，受方案層級限制：192 kbps MP3 需要 Creator 層級以上，44.1 kHz PCM 需要 Pro 層級以上。值遵循 `codec_sample_rate_bitrate`；例如 `mp3_22050_32` 指定取樣率 22.05 kHz、位元率 32 kbs 的 MP3。Twilio 音訊輸入通常使用 μ-law；此格式也寫作 mu-law，或近似寫作 u-law。 |

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

### JavaScript

```javascript
const API = "https://api.doitong.ru/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.ru/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.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": "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.
