# Seedance 2.0 Fast Text to Video API

> Дыбысы бар 480p және 720p клиптерге арналған жылдамырақ әрі арзанырақ Seedance 2.0

Seedance 2.0-нің жылдам деңгейі толық модельдің көпкөріністі баяндауы мен синхрондалған аудиосын бағаның шамамен 80 пайызымен ұсынады, бірақ 480p және 720p форматтарымен шектеледі. 4–15 секунд немесе автоматты ұзақтық, жеті кадр пішімі. Соңғы рендерге дейін нобайлар мен әлеуметтік желі үзінділеріне қолайлы.

## Pricing

Price: **from $0.113 / second (4 s ≈ $0.452)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 15).

The full example input below costs $0.565 = 565 API credits (5 s × 113 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/bytedance/seedance-2.0/fast/text-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

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  |  | Бейне генерациясын бағыттайтын мәтіндік нұсқау. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Шығыс ажыратымдылығы: 480p генерация жылдамдығына, 720p теңгерімді таңдауға басымдық береді. |
| `duration` |  | enum (string) | no | `auto` | `auto`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15` | Бейне ұзақтығын таңдау: `auto` нұсқауға сүйеніп таңдауды модельге береді, ал нақты ұзақтық 4–15 секунд аралығында болуы керек. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Шығыс арақатынасы: 16:9 альбомдық, 9:16 портреттік/тік, 1:1 шаршы, 21:9 кинематографиялық ультракең бейне береді. Арақатынасты модель таңдауы үшін `auto` таңдаңыз. |
| `generate_audio` |  | boolean | no | `true` |  | Бейнеге синхрондалған аудио қосу үшін осыны қосыңыз. Генерацияланған аудио ерін қимылдарына сәйкестендірілген сөйлеуді, қоршаған орта үнін және дыбыс әсерлерін қамтиды. |
| `bitrate_mode` |  | enum (string) | no | `standard` | `standard`, `high` | Шығыс кодтау битрейтін таңдаңыз: 'standard' әдепкі мәнді сақтайды, ал 'high' файл өлшемін үлкейту есебінен кодтау сапасын жақсартуды сұрайды. |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | Бейне кодегін таңдау: `auto` әдепкі кодек әрекетін өзгертпейді, `H264` H.264 таңдайды, `H265` H.265 таңдайды. |

## Example input

Required parameters only:

```json
{
  "prompt": "A paper boat sails down a rain-filled gutter past glowing shop windows, camera follows at water level"
}
```

A fuller example:

```json
{
  "prompt": "A paper boat sails down a rain-filled gutter past glowing shop windows, camera follows at water level",
  "duration": 5,
  "resolution": "480p"
}
```

## 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/bytedance/seedance-2.0/fast/text-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A paper boat sails down a rain-filled gutter past glowing shop windows, camera follows at water level",
    "duration": 5,
    "resolution": "480p"
  }'

# 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/bytedance/seedance-2.0/fast/text-to-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A paper boat sails down a rain-filled gutter past glowing shop windows, camera follows at water level",
    "duration": 5,
    "resolution": "480p"
  }),
});
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 paper boat sails down a rain-filled gutter past glowing shop windows, camera follows at water level",
    "duration": 5,
    "resolution": "480p",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/bytedance/seedance-2.0/fast/text-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.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": "bytedance/seedance-2.0/fast/text-to-video",
      "input": {
        "prompt": "A paper boat sails down a rain-filled gutter past glowing shop windows, camera follows at water level",
        "duration": 5,
        "resolution": "480p"
      },
      "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.
