# ACE Step Audio Inpaint API

> Yeni etiketler ve sözler kullanarak mevcut bir ses dosyasının seçilen zaman aralığını yeniden oluşturur

Bir `audio_url` alır ve yalnızca `start_time` ile `end_time` arasındaki bölümü yeniden yazar; her ikisi de 0 ile 240 arasında saniye cinsinden ölçülür. Her zaman klibin başlangıcına veya sonuna göre ayarlanabilir. Yeni `tags` ve `lyrics` değiştirilen bölümü yönlendirir, `variance` ise sonucun çeşitliliğini kontrol eder. Standart yönlendirme ve adım ayarları kullanılabilir.

- Price per second of your input audio: $0.0002 / second of input audio (cheapest run $0.001 (1 API credit))
- Run: `POST https://api.doitong.ru/v1/run/ace-step/audio-inpaint`

## Pricing

Price: **$0.0002 / second of input audio**. Price per second of your input 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 $0.002 = 2 API credits (10 s input audio × $0.0002).

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/ace-step/audio-inpaint` 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

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `audio_url` | `audio` | string (audio URL) | yes |  |  | Inpainting için ses dosyası URL'si. |
| `start_time_relative_to` |  | enum (string) | no | `start` | `start`, `end` | Başlangıç zamanı için referans noktası: sesin başlangıcı veya sonu. |
| `start_time` |  | number | no | `0` | 0 – 240 | Saniye cinsinden ölçülen inpainting başlangıç zamanı. |
| `end_time_relative_to` |  | enum (string) | no | `start` | `start`, `end` | Bitiş zamanı için referans noktası: sesin başlangıcı veya sonu. |
| `end_time` |  | number | no | `30` | 0 – 240 | Saniye cinsinden ölçülen inpainting bitiş zamanı. |
| `tags` |  | string | yes |  |  | Virgülle ayrılmış türler olarak sağlanan ses stili etiketleri; bunları sağlamak için alternatif olarak `prompt` kullanılabilir. |
| `lyrics` |  | string | no | `` |  | [verse], [chorus] ve [bridge] gibi denetimlerle bölümlere ayrılmış sözler. Söylenen sözleri olmayan ses için bu girdiyi atlayın veya yalnızca [inst] ya da [instrumental] sağlayın. |
| `variance` |  | number | no | `0.5` | 0 – 1 | Inpainting varyansı, sonuçların ne kadar çeşitli olabileceğini belirler; artırılması daha fazla çeşitlilik oluşturabilir. |
| `number_of_steps` |  | integer | no | `27` | 3 – 60 | Ses üretimi sırasında kullanılan adım sayısı. |
| `seed` |  | integer \| null | no |  |  | Tekrarlanabilir üretim için kullanılan seed; bir değer sağlamadığınız sürece rastgele seçilir. |
| `scheduler` |  | enum (string) | no | `euler` | `euler`, `heun` | Üretim sırasında kullanılan scheduler. |
| `guidance_type` |  | enum (string) | no | `apg` | `cfg`, `apg`, `cfg_star` | Üretim sırasında kullanılan CFG türü. |
| `granularity_scale` |  | integer | no | `10` | -100 – 100 | Üretim sırasında uygulanan ayrıntı ölçeği. Artırılması artefaktları azaltabilir. |
| `guidance_interval` |  | number | no | `0.5` | 0 – 1 | Yönlendirme alan üretim çizelgesi bölümü: 0.5 seçildiğinde bu bölüm 0.25 * infer_steps ile 0.75 * infer_steps arasındaki adımlarla sınırlanır; başlangıç ve son yönlendirilmez. |
| `guidance_interval_decay` |  | number | no | `0` | 0 – 1 | Üretim aralığındaki yönlendirme azalması: 0.0 azalmayı devre dışı bırakır; aksi durumda ölçek, bu aralık boyunca guidance_scale değerinden min_guidance_scale değerine düşer. |
| `guidance_scale` |  | number | no | `15` | 0 – 200 | Üretim sırasında uygulanan yönlendirme ölçeği. |
| `minimum_guidance_scale` |  | number | no | `3` | 0 – 200 | Üretim sırasında azalma sonrasında ulaşılan en düşük yönlendirme ölçeği. |
| `tag_guidance_scale` |  | number | no | `5` | 0 – 10 | Üretim sırasında uygulanan etiket yönlendirme ölçeği. |
| `lyric_guidance_scale` |  | number | no | `1.5` | 0 – 10 | Üretim sırasında uygulanan söz yönlendirme ölçeği. |

File parameters (`audio`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## Example input

Required parameters only:

```json
{
  "tags": "lofi, hiphop, drum and bass, trap, chill",
  "audio": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
}
```

A fuller example:

```json
{
  "tags": "lofi, hiphop, drum and bass, trap, chill",
  "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
}
```

## 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/ace-step/audio-inpaint?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "tags": "lofi, hiphop, drum and bass, trap, chill",
    "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
  }'

# 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/ace-step/audio-inpaint?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({

  }),
});
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 = {
    "tags": "lofi, hiphop, drum and bass, trap, chill",
    "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/ace-step/audio-inpaint", 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": "ace-step/audio-inpaint",
      "input": {
        "tags": "lofi, hiphop, drum and bass, trap, chill",
        "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
      },
      "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.
