# Elevenlabs Music API

> Text-to-music generator driven by a prompt or a structured composition plan, with instrumental option

Composes music from a text `prompt` of up to 4100 characters, or from a detailed `composition_plan`. With a prompt, `music_length_ms` can range from 3000 to 600000 milliseconds, and `force_instrumental` guarantees no vocals. `respect_sections_durations` governs how strictly plan sections are timed. Many codec and sample-rate choices are offered through `output_format`.

- 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/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 | Text description of the desired music. |
| `composition_plan` |  | object {positive_global_styles, negative_global_styles, sections} \| null | no |  |  | Plan defining the music's composition. |
| `composition_plan.positive_global_styles` |  | array of string | yes |  |  | Styles to include throughout the song. |
| `composition_plan.negative_global_styles` |  | array of string | yes |  |  | Styles to exclude throughout the song. |
| `composition_plan.sections` |  | array of object {section_name, positive_local_styles, negative_local_styles, duration_ms, lines} | yes |  |  | Sections making up the song. |
| `composition_plan.sections[].section_name` |  | string | yes |  | 1 – 100 characters | Section name, with a length from 1 to 100 characters. |
| `composition_plan.sections[].positive_local_styles` |  | array of string | yes |  |  | Styles to include within this section. |
| `composition_plan.sections[].negative_local_styles` |  | array of string | yes |  |  | Styles to exclude within this section. |
| `composition_plan.sections[].duration_ms` |  | integer | yes |  | 3,000 – 120,000 | Section length in milliseconds, ranging from 3000 ms to 120000 ms. |
| `composition_plan.sections[].lines` |  | array of string | yes |  |  | Lyrics for this section, limited to 200 characters per line. |
| `music_length_ms` |  | integer \| null | no |  | 3,000 – 600,000 | Optional song duration in milliseconds, ranging from 3000 ms to 600000 ms, applicable only when using a prompt. When omitted, the model determines the duration from the prompt. |
| `force_instrumental` |  | boolean | no | `false` |  | Instrumental-only control, available only when using a prompt. Setting it to true guarantees instrumental output; false allows either instrumental or non-instrumental music according to the prompt. |
| `respect_sections_durations` |  | boolean | no | `true` |  | Section-timing enforcement for `composition_plan`, with no effect outside that plan. False allows the model to vary individual section lengths, generally improving quality and latency without changing the plan's total song duration; true instead enforces every section's `duration_ms` exactly. |
| `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` | Audio output format, subject to tier requirements: 192 kbps MP3 needs Creator tier or higher, and 44.1 kHz PCM needs Pro tier or higher. Values follow `codec_sample_rate_bitrate`; `mp3_22050_32`, for example, specifies a 22.05 kHz MP3 at 32 kbs. For Twilio audio input, μ-law is commonly used; this format is also written mu-law or approximated as 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.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.
