# Elevenlabs Music v2 API

> Komponéiert Musek aus engem Textprompt oder chunk-baséierte Kompositiounsplang, mat optionalem reng instrumentale Modus

Erstellt Musek aus engem Text-`prompt` mat bis zu 4100 Zeechen oder engem strukturéierte `composition_plan`. `music_length_ms` setzt mat engem Prompt d'Längt tëscht 3000 an 600000 ms; `force_instrumental` ewechhëlt de Gesang. `output_format` wielt Codec, Sample-Rate a Bitrate, inklusiv MP3- a PCM-Optiounen. `seed` funktionéiert nëmme mat engem Kompositiounsplang.

- 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/v2`

## 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 $1.20 = 1200 API credits (2 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/v2` 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 | Textbeschreiwung vun der gewënschter Musek. |
| `composition_plan` |  | object {chunks} \| null | no |  |  | Musekskompositiounsplang, a Chunks organiséiert. |
| `composition_plan.chunks` |  | array of object {text, duration_ms, positive_styles, negative_styles, context_adherence, audio_reference} | yes |  | 1 – 30 items | Geuerdent Chunks fir d'Generatioun, limitéiert op 30 Chunks mat enger kombinéierter Dauer vun 3000 ms bis 600000 ms. |
| `composition_plan.chunks[].text` |  | string | yes |  |  | Text fir d'Chunk-Generatioun, limitéiert op 30 Linne mat bis zu 200 Zeechen. Lyrics kënnen inline Uweisungen a geschwongene Klammeren enthalen, wéi {scratching}, a kënnen engem optionalen Ufanksnumm an eckege Klammeren follegen, wéi [Verse 1]. Dëse Sektiounsnumm muss 1–100 Zeechen enthalen. |
| `composition_plan.chunks[].duration_ms` |  | integer | yes |  | 3,000 – 120,000 | Längt vum Chunk a Millisekonnen, vun 3000 ms bis 120000 ms. |
| `composition_plan.chunks[].positive_styles` |  | array of string | yes |  |  | Gewënschte Stiler a musikalesch Uweisunge fir dëse Chunk, mat dem gréissten Afloss vun den Auswieler vum éischte Chunk: Si leeën de Gesamtgenre an den Toun vum Lidd fest. Spéider Chunks kënnen d'Musek weiderentwéckelen, Nuancen dobäisetzen oder d'Richtung änneren; englesch Beschreiwunge funktionéieren am beschten. |
| `composition_plan.chunks[].negative_styles` |  | array of string \| null | no |  |  | Musikalesch Stiler an Uweisungen, déi an dësem Chunk ze vermeiden sinn; gitt nëmmen explizit Ausschlëss un, soss ass eng eidel Lëscht e gudde Standard. |
| `composition_plan.chunks[].context_adherence` |  | enum (string) \| null | no |  | `low`, `medium`, `high` | Kontextkonformitéit balanséiert kreativ Fräiheet mat der Konsequenz zu benachbarte Chunks: wielt héich fir Konsequenz oder niddreg fir méi kreativ Ofwäichungen z'erlaben. |
| `composition_plan.chunks[].audio_reference` |  | object {audio_url, start_ms, end_ms, strength} \| null | no |  |  | Audio-Clip fir d'Konditionéierung vum Stil vun dësem Chunk; fir dat ganzt Lidd ze gestalten, gitt en am éischte Chunk un. Dës Plaz huet de gréissten Afloss, well seng Referenz all spéider Chunk beaflosst. |
| `music_length_ms` |  | integer \| null | no |  | 3,000 – 600,000 | Optional Dauer vum Lidd a Millisekonnen, vun 3000 ms bis 600000 ms, nëmme bei Benotzung vun engem Prompt. Wann ewechgelooss, bestëmmt d'Modell d'Dauer aus dem Prompt. |
| `force_instrumental` |  | boolean | no | `false` |  | Kontroll nëmme fir Instrumentalmusek, nëmme bei Benotzung vun engem Prompt verfügbar. true garantéiert en instrumentalen Output; false erlaabt jee no Prompt instrumental oder net-instrumental Musek. |
| `seed` |  | integer \| null | no |  |  | Initialiséierungs-Seed fir d'Museksgeneratioun, nëmmen zesumme mat `composition_plan` benotzbar, fir méi Konsequenz bei Laf mat identesche Parameteren a Seed. Exakt identesch Resultater sinn net garantéiert. |
| `output_format` |  | enum (string) | no | `mp3_48000_192` | `mp3_22050_32`, `mp3_24000_48`, `mp3_44100_32`, `mp3_44100_64`, `mp3_44100_96`, `mp3_44100_128`, `mp3_44100_192`, `mp3_48000_128`, `mp3_48000_192`, `mp3_48000_240`, `mp3_48000_320`, `pcm_8000`, `pcm_16000`, `pcm_22050`, `pcm_24000`, `pcm_32000`, `pcm_44100`, `pcm_48000`, `ulaw_8000`, `alaw_8000`, `opus_48000_32`, `opus_48000_64`, `opus_48000_96`, `opus_48000_128`, `opus_48000_192` | Wielt d'Format vum generéierten Audio mam Muster codec_sample_rate_bitrate. Twilio-Audio-Inputen benotzen dacks μ-law, och mu-law genannt oder als u-law approximéiert; e MP3-Beispill ass mp3_22050_32, wat eng Sampling-Rate vun 22.05 kHz an e Bitrate vun 32 kbs bedeit. |

## 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/v2?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/v2?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/v2", 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/v2",
      "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.
