# Personaplex API

> Konverzační model převodu řeči na řeč, který odpovídá na mluvený zvuk zvolenou personou a hlasem

Přijímá řeč uživatele přes `audio_url` a odpovídá generovanou řečí, která se vrací spolu s přepisem odpovědi a její délkou. Textový `prompt` definuje personu a `voice` volí přednastavený hlas. Alternativně `voice_audio_url` klonuje hlas ze vzorku, přičemž se doporučuje alespoň 10 sekund čisté řeči. Vzorkování lze nastavit pomocí teploty a hodnot top-k.

- Model id: `personaplex`
- Made by: NVIDIA
- Category: Audio
- Output: audio
- Price per second of your input audio: $0.001 / second of input audio (cheapest run $0.001 (1 API credit))
- Run: `POST https://api.doitong.com/v1/run/personaplex`
- Quote: `POST https://api.doitong.com/v1/quote/personaplex`
- Docs page: https://doitong.com/cs/developers/models/personaplex

## Pricing

Price: **$0.001 / 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 $0.01 = 10 API credits (10 s input audio × $0.001).

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/personaplex` 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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | no | `You are a wise and friendly teacher. Answer questions or provide advice in a clear and engaging way.` |  | Textový prompt definující personu AI a kontext konverzace. |
| `voice` |  | enum (string) | no | `NATF2` | `NATF0`, `NATF1`, `NATF2`, `NATF3`, `NATM0`, `NATM1`, `NATM2`, `NATM3`, `VARF0`, `VARF1`, `VARF2`, `VARF3`, `VARF4`, `VARM0`, `VARM1`, `VARM2`, `VARM3`, `VARM4` | ID hlasu odpovědi AI, přepsané pomocí voice_audio_url, pokud je zadáno. Jeho kódy rozlišují přirozený hlas (NAT) od variabilního (VAR) a ženský (F) od mužského (M). |
| `voice_audio_url` |  | string (audio URL) \| null | no |  |  | URL vzorku pro klonování hlasu; doporučuje se čistá řeč trvající alespoň 10 sekund. Vzorek se klonuje za běhu a nahrazuje přednastavený 'voice' pro odpověď AI. |
| `temperature_audio` |  | number | no | `0.8` | 0 – 2 | Teplota použitá při vzorkování zvuku; její zvýšení přináší rozmanitější výsledky. |
| `temperature_text` |  | number | no | `0.7` | 0 – 2 | Teplota použitá při vzorkování textu; její zvýšení přináší rozmanitější výsledky. |
| `top_k_audio` |  | integer | no | `250` | 1 – 2,048 | Nastavení Top-K používané pro vzorkování zvukových tokenů. |
| `top_k_text` |  | integer | no | `25` | 1 – 1,000 | Nastavení Top-K používané pro vzorkování textových tokenů. |
| `seed` |  | integer \| null | no |  |  | Seed řídící náhodnost pro reprodukovatelné výsledky. |
| `audio_url` | `audio` | string (audio URL) | yes |  |  | URL vstupního zvuku obsahujícího řeč uživatele. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Kontrolu lze uvolnit nastavením na false, pokud je volající autorizován. |

File parameters (`voice_audio_url`, `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
{
  "audio": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
}
```

A fuller example:

```json
{
  "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.com/v1/run/personaplex?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "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.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/personaplex?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
  }),
});
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 = {
    "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/personaplex", 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": "personaplex",
      "input": {
        "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.
