# Elevenlabs Music v2 API

> Semur tónlist úr textaprompti eða kubbaskiptri tónsmíðaáætlun, með valfrjálsri stillingu fyrir hljóðfæraleik eingöngu

Býr til tónlist úr texta `prompt` með allt að 4100 stöfum eða úr skipulagðri `composition_plan`. `music_length_ms` stillir lengdina á bilinu 3000 til 600000 ms þegar hún er notuð með kvaðningu og `force_instrumental` fjarlægir söng. `output_format` velur kóðun, sýnatökutíðni og bitahraða, þar á meðal MP3- og PCM-valkosti. `seed` virkar aðeins með composition plan.

## 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 | Textalýsing á tónlistinni sem óskað er eftir. |
| `composition_plan` |  | object {chunks} \| null | no |  |  | Tónsmíðaáætlun skipulögð í bita. |
| `composition_plan.chunks` |  | array of object {text, duration_ms, positive_styles, negative_styles, context_adherence, audio_reference} | yes |  | 1 – 30 items | Raðaðir bitar sem notaðir eru við efnisgerð, takmarkaðir við 30 bita með samanlagðri lengd frá 3000 ms til 600000 ms. |
| `composition_plan.chunks[].text` |  | string | yes |  |  | Texti fyrir bitagerð, takmarkaður við 30 línur með allt að 200 stöfum hver. Texti má innihalda innfelldar leiðbeiningar í slaufusviga, svo sem {scratching}, og má fylgja valfrjálsu upphafsheiti hluta í hornklofum, svo sem [Verse 1]. Heitið verður að innihalda 1–100 stafi. |
| `composition_plan.chunks[].duration_ms` |  | integer | yes |  | 3,000 – 120,000 | Lengd bita í millisekúndum, frá 3000 ms til 120000 ms. |
| `composition_plan.chunks[].positive_styles` |  | array of string | yes |  |  | Æskilegir stílar og tónlistarlegar leiðbeiningar fyrir þennan bita, þar sem val fyrri bitans hefur mest áhrif: þau móta heildarstefnu og tón lagsins. Síðari bitar geta þróað tónlistina, bætt við blæbrigðum eða breytt stefnu; enskar lýsingar virka best. |
| `composition_plan.chunks[].negative_styles` |  | array of string \| null | no |  |  | Tónlistarlegir stílar og leiðbeiningar sem á að forðast í þessum bita; tilgreindu aðeins atriði sem á að útiloka sérstaklega, annars er gott sjálfgefið að hafa listann tóman. |
| `composition_plan.chunks[].context_adherence` |  | enum (string) \| null | no |  | `low`, `medium`, `high` | Samhengisfylgni vegur skapandi frelsi á móti samræmi við aðliggjandi bita: veldu hátt gildi fyrir samræmi eða lágt gildi til að leyfa meiri skapandi frávik. |
| `composition_plan.chunks[].audio_reference` |  | object {audio_url, start_ms, end_ms, strength} \| null | no |  |  | Hljóðbútur sem skilyrðir stíl þessa bita; til að móta allt lagið skaltu gefa hann upp fyrir fyrsta bitann. Sú staðsetning hefur mest áhrif vegna þess að viðmið hans hefur áhrif á alla síðari bita. |
| `music_length_ms` |  | integer \| null | no |  | 3,000 – 600,000 | Valfrjáls lengd lags í millisekúndum, frá 3000 ms til 600000 ms, aðeins notuð með kvaðningu. Þegar hún er ekki gefin ákvarðar líkanið lengdina út frá kvaðningunni. |
| `force_instrumental` |  | boolean | no | `false` |  | Stýring fyrir eingöngu hljóðfæraleik, aðeins tiltæk með kvaðningu. Að stilla á true tryggir hljóðfæraúttak; false leyfir hljóðfæra- eða söngtónlist samkvæmt kvaðningunni. |
| `seed` |  | integer \| null | no |  |  | Sáðkorn fyrir frumstillingu tónlistargerðar, aðeins nothæft með `composition_plan`, til að bæta samræmi milli keyrslna með sömu færibreytum og sáðkorni. Ekki er tryggt að niðurstöður endurtaki sig nákvæmlega. |
| `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` | Veldu snið hljóðsins sem verður til með mynstrinu codec_sample_rate_bitrate. Twilio-hljóðinntak notar oft μ-law, einnig skrifað mu-law eða nálgað sem u-law; MP3-dæmið mp3_22050_32 tilgreinir 22.05 kHz sýnatökuhraða og bitahraða 32 kbs. |

## 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.
