# Mirage Avatar X API

> Mluvící video avatara Avatar X řízené vaším zvukem a obrázkem, videem nebo referencí stock avatara

Vytváří video avatara se synchronizací rtů z `audio_url` (3 až 180 sekund). Vizuální podobu poskytuje `video_reference_url`, `image_reference_url` nebo stock `avatar`; pokud jsou zadány obě reference, přednost má video. Volba avatara poskytuje pouze obraz, nikoli zvuk. Referenční adresy URL musí být veřejně dostupné přes HTTPS.

- Model id: `mirage-api/avatar-x/reference-to-video`
- Made by: Mirage
- Category: Lipsync & Avatars
- Output: video
- Price per second of your input audio: $0.30 / second of input audio (cheapest run $0.30 (300 API credits))
- Run: `POST https://api.doitong.com/v1/run/mirage-api/avatar-x/reference-to-video`
- Quote: `POST https://api.doitong.com/v1/quote/mirage-api/avatar-x/reference-to-video`
- Docs page: https://doitong.com/cs/developers/models/mirage-api/avatar-x/reference-to-video

## Pricing

Price: **$0.30 / 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 $3.00 = 3000 API credits (10 s input audio × $0.30).

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/mirage-api/avatar-x/reference-to-video` 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 |  |  | Veřejně dostupná HTTPS adresa zvuku, který řídí vygenerované video, přístupná bez autorizačních hlaviček nebo cookies. Přijímané formáty zvuku jsou FLAC, Opus nebo Vorbis, AAC nebo ALAC, PCM WAV nebo AIFF a MP3. Soubor musí obsahovat jediný mono nebo stereo stream, trvat 3–180 sekund, mít nejvýše 64 MiB a vzorkovací frekvenci 8–48 kHz. |
| `video_reference_url` |  | string \| null | no |  |  | Veřejně dostupná HTTPS URL referenčního videa bez autorizačních hlaviček nebo cookies. Soubor musí obsahovat přesně jeden video stream a alespoň jeden vhodný 1sekundový úsek pro použití jako reference; zvuk se ignoruje. Přijímané soubory jsou .mp4, .mov nebo .m4v s H.264, H.265/HEVC nebo ProRes, případně .webm s VP8 nebo VP9; délka musí být 1 až 120 sekund, velikost nejvýše 1 GiB a poměr stran zobrazení musí být v rozmezí 5 % od 9:16 nebo 16:9. Pokud je zadán také image_reference_url, přednost má video. |
| `avatar` |  | enum (string) \| null | no |  | `None`, `Ayesha`, `Ayesha (16:9)`, `Farhan`, `Farhan (16:9)`, `Giulia`, `Giulia (16:9)`, `Jasmine`, `Jasmine (16:9)`, `Luke`, `Luke (16:9)`, `Maya`, `Maya (16:9)`, `Michael`, `Michael (16:9)`, `Neha`, `Neha (16:9)`, `Tariq`, `Tariq (16:9)`, `Valerie`, `Valerie (16:9)` | Výběr vizuálu z nabídky použitý pouze tehdy, když není zadána reference obrázku ani videa; None i výchozí hodnota jej ponechají nenastavený. Tento vizuál nikdy nedodává zvuk, který vždy pochází z audio_url. Vizuál vyberete tak, že zobrazíte možnosti v [katalogu avatarů](https://captions.ai/help/docs/api/actor-catalog) a zkopírujete přesnou hodnotu Avatar. |
| `image_reference_url` |  | string \| null | no |  |  | Veřejně dostupná HTTPS URL referenčního obrázku bez cookies nebo autorizačních hlaviček; zadání video_reference_url způsobí její ignorování. Přijímá jeden statický obrázek ve formátu .jpg, .jpeg, .png nebo .webp, s velikostí nejvýše 25 MiB a 25 megapixelů. Kratší strana musí mít alespoň 512 px a žádná strana nesmí překročit 8192 px; poměr stran musí být v rozmezí 5 % od 9:16 nebo 16:9. |

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
{
  "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/mirage-api/avatar-x/reference-to-video?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/mirage-api/avatar-x/reference-to-video?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/mirage-api/avatar-x/reference-to-video", 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": "mirage-api/avatar-x/reference-to-video",
      "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.
