## Pricing

Price: **$0.025 / 1000 characters**. Billed per character of `text` (the price is per 1000 characters).

The full example input below costs $0.002 = 2 API credits (50 characters × 25 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/chatterbox/text-to-speech/multilingual` 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 |
|---|---|---|---|---|---|---|
| `text` |  | string | yes |  | ≤ 300 characters | কথ্য সংশ্লেষণের টেক্সট, 300 অক্ষরে সীমিত এবং 23টি ভাষা সমর্থন করে। উপলভ্য ভাষার মধ্যে রয়েছে English ও French; German, Spanish, Italian ও Portuguese; Hindi ও Arabic; Chinese, Japanese ও Korean, এছাড়াও আরও কিছু ভাষা। |
| `voice` |  | string | no | `english` |  | সংশ্লেষণের ভাষা কোড; custom ব্যবহারের জন্য একটি অডিও URL এবং custom_audio_language-এর একটি নির্বাচন—দুটিই প্রয়োজন। |
| `custom_audio_language` |  | enum (string) \| null | no |  | `english`, `arabic`, `danish`, `german`, `greek`, `spanish`, `finnish`, `french`, `hebrew`, `hindi`, `italian`, `japanese`, `korean`, `malay`, `dutch`, `norwegian`, `polish`, `portuguese`, `russian`, `swedish`, `swahili`, `turkish`, `chinese` | ভয়েস কাস্টম URL হিসেবে দেওয়া হলেই এই ভাষা সেটিং প্রযোজ্য; অন্যথায় এটি উপেক্ষা করা হয়। ওই কাস্টম অডিওতে ব্যবহৃত ভাষা নির্দিষ্ট করুন। |
| `exaggeration` |  | number | no | `0.5` | 0.25 – 2 | 0.5-এর neutral সেটিংয়ের তুলনায় কথার অভিব্যক্তি ও আবেগের তীব্রতা। মান বাড়ালে 0.25–2.0 সীমার মধ্যে অভিব্যক্তিশীলতা বাড়ে, তবে চরম সেটিংয়ে অস্থিতিশীলতা দেখা দিতে পারে। |
| `temperature` |  | number | no | `0.8` | 0.05 – 2 | জেনারেশনের র‍্যান্ডমনেস 0.05 থেকে 2.0-এর মধ্যে সেট করে কথনভঙ্গির বৈচিত্র্য নিয়ন্ত্রণ করুন; মান বাড়ালে বৈচিত্র্য বাড়ে। |
| `cfg_scale` |  | number | no | `0.5` | 0 – 1 | কনফিগারেশন/গতির জন্য জেনারেশন নির্দেশনার ওজন। ভাষা স্থানান্তরের ক্ষেত্রে, 0.0 মূল উচ্চারণের প্রভাব সীমিত রাখতে সাহায্য করে; সম্পূর্ণ পরিসর 0.0–1.0। |
| `seed` |  | integer \| null | no |  |  | জেনারেশন সিডের দুটি আচরণ: 0 র‍্যান্ডম জেনারেশন বেছে নেয়, আর নির্দিষ্ট কোনো সংখ্যা দিলে একই আউটপুট পুনরায় তৈরি করা যায়। |

## Example input

Required parameters only:

```json
{
  "text": "Hello from Doitong. This is a short test sentence."
}
```

A fuller example:

```json
{
  "text": "Hello from Doitong. This is a short test sentence."
}
```

## 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/chatterbox/text-to-speech/multilingual?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "text": "Hello from Doitong. This is a short test sentence."
  }'

# 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/chatterbox/text-to-speech/multilingual?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "text": "Hello from Doitong. This is a short test sentence."
  }),
});
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 = {
    "text": "Hello from Doitong. This is a short test sentence.",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/chatterbox/text-to-speech/multilingual", 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": "chatterbox/text-to-speech/multilingual",
      "input": {
        "text": "Hello from Doitong. This is a short test sentence."
      },
      "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.
