# Stable Audio 3 Small SFX Text to Audio API

> متن سے صوتی اثرات بنانے والا چھوٹا ڈسٹلڈ ماڈل، ڈیفالٹ 8 مراحل، 120 سیکنڈ تک کے کلپ

ٹیکسٹ `prompt` سے ساؤنڈ ایفیکٹس بناتا ہے، ایک اختیاری `negative_prompt` کے ساتھ۔ `duration` 1 سے 120 سیکنڈ ہو سکتا ہے۔ یہ پوسٹ ٹرینڈ ورژن ڈیفالٹ طور پر 8 سیمپلنگ اسٹیپس استعمال کرتا ہے، اور گائیڈنس کا بہت کم اثر ہوتا ہے۔ آؤٹ پٹ mp3، wav، flac، ogg، opus، m4a یا aac ہو سکتا ہے۔

- Output: audio
- Price: $0.0206 / request (cheapest run $0.021 (21 API credits))
- Run: `POST https://api.doitong.ru/v1/run/stable-audio-3/small/sfx/text-to-audio`
- Quote: `POST https://api.doitong.ru/v1/quote/stable-audio-3/small/sfx/text-to-audio`

## Pricing

Price: **$0.0206 / request**. Billed once per request.

The full example input below costs $0.021 = 21 API credits (1 request × 20.6 API credits).

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/stable-audio-3/small/sfx/text-to-audio` 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 |
|---|---|---|---|---|---|---|
| `negative_prompt` |  | string | no | `` |  | آؤٹ پٹ میں ناپسندیدہ خصوصیات بیان کرنے والا متن۔ |
| `duration` |  | number | no | `30` | 1 – 120 | تیار کردہ آڈیو کی لمبائی، سیکنڈ میں۔ |
| `num_inference_steps` |  | integer | no | `8` | 1 – 100 | sampling iteration count، ڈیفالٹ 8؛ کیونکہ distilled، post-trained checkpoints وہاں پہلے ہی اچھی quality حاصل کرتے ہیں، اور اضافی iterations کا فائدہ کم ہوتا ہے۔ |
| `guidance_scale` |  | number | no | `1` | 0 – 25 | صرف base checkpoints کے لیے classifier-free guidance strength؛ distilled checkpoints متاثر نہیں ہوتے۔ متعلقہ checkpoints پر اسے بڑھانے سے پرامپٹ سے مطابقت مضبوط ہوتی ہے۔ |
| `seed` |  | integer \| null | no |  |  | قابل تکرار نتائج کے لیے random generator seed؛ اسے چھوڑنے پر random seed منتخب ہوتا ہے۔ |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | فعال ہونے پر LLM کے ذریعے پرامپٹ کی توسیع، جس سے تفصیل اور نتیجے کا معیار بہتر ہوتا ہے۔ |
| `enable_safety_checker` |  | boolean | no | `true` |  | NSFW مواد کی safety checking۔ |
| `output_format` |  | enum (string) | no | `mp3` | `mp3`, `wav`, `flac`, `ogg`, `opus`, `m4a`, `aac` | نتیجے کے آڈیو کے لیے استعمال ہونے والا container format۔ |
| `bitrate` |  | string | no | `192k` |  | آؤٹ پٹ آڈیو bitrate، wav یا flac کے لیے نظرانداز ہوتا ہے کیونکہ یہ lossless ہیں۔ mp3، aac یا opus جیسے compressed formats کے لیے '192k' یا '320k' کی شکل میں قدر فراہم کریں۔ |
| `prompt` |  | string | yes |  |  | مطلوبہ آڈیو مواد بیان کرنے والا متن۔ |

## Example input

Required parameters only:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

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/stable-audio-3/small/sfx/text-to-audio?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/stable-audio-3/small/sfx/text-to-audio?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/stable-audio-3/small/sfx/text-to-audio", 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": "stable-audio-3/small/sfx/text-to-audio",
      "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.
