# Async Text to Speech Pro V1.0 API

> آواز کے انتخاب، اختیاری آواز کی کلوننگ اور چھ لازمی زبان کے اختیارات کے ساتھ متن سے آواز

`transcript` کو منتخب `voice` آبجیکٹ کے ذریعے آواز میں تبدیل کرتا ہے۔ اختیاری `language` پیرامیٹر انگریزی، فرانسیسی، ہسپانوی، جرمن، اطالوی یا پرتگالی میں تخلیق کو لازمی بناتا ہے۔ `output_format` آبجیکٹ آڈیو کو ترتیب دیتا ہے، اور نتیجے میں آڈیو فائل، اس کی MIME قسم اور بائٹس میں سائز شامل ہوتا ہے۔ مخصوص آواز منتخب کرنے والی وائس اوورز کے لیے موزوں ہے۔

- Model id: `async/tts-pro/v1.0`
- Made by: Async
- Category: Text to Speech
- Output: audio
- Price: $0.01 / 1000 characters (cheapest run $0.01 (10 API credits))
- Run: `POST https://api.doitong.com/v1/run/async/tts-pro/v1.0`
- Quote: `POST https://api.doitong.com/v1/quote/async/tts-pro/v1.0`

## Pricing

Price: **$0.01 / 1000 characters**. Billed per character of `transcript` (the price is per 1000 characters).

The full example input below costs $0.001 = 1 API credit (50 characters × 10 API credits / 1000 characters).

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/async/tts-pro/v1.0` 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.

## Example input

Required parameters only:

```json
{
  "transcript": "Hello from Doitong. This is a short test sentence.",
  "voice": {
    "name": "Jennie"
  }
}
```

A fuller example:

```json
{
  "transcript": "Hello from Doitong. This is a short test sentence.",
  "voice": {
    "name": "Jennie"
  }
}
```

## 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/async/tts-pro/v1.0?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "transcript": "Hello from Doitong. This is a short test sentence.",
    "voice": {
      "name": "Jennie"
    }
  }'

# 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/async/tts-pro/v1.0?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "transcript": "Hello from Doitong. This is a short test sentence.",
    "voice": {
      "name": "Jennie"
    }
  }),
});
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 = {
    "transcript": "Hello from Doitong. This is a short test sentence.",
    "voice": {
        "name": "Jennie",
    },
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/async/tts-pro/v1.0", 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": "async/tts-pro/v1.0",
      "input": {
        "transcript": "Hello from Doitong. This is a short test sentence.",
        "voice": {
          "name": "Jennie"
        }
      },
      "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.
