## 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 |  |  | ویڈیو تخلیق کی رہنمائی کرنے والا متنی پرامپٹ۔ |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | آؤٹ پٹ ریزولوشن: 480p رفتار کو ترجیح دیتا ہے، جبکہ 720p متوازن انتخاب فراہم کرتا ہے۔ |
| `duration` |  | enum (string) | no | `auto` | `auto`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15` | ویڈیو کی لمبائی: `auto` پرامپٹ کے ذریعے ماڈل کو انتخاب سونپتا ہے، جبکہ واضح دورانیہ 4 سے 15 سیکنڈ کے درمیان ہونا چاہیے۔ |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | آؤٹ پٹ aspect ratio: 16:9 landscape، 9:16 portrait/vertical، 1:1 square اور 21:9 cinematic ultrawide فراہم کرتا ہے۔ ماڈل کو ratio منتخب کرنے دینے کے لیے `auto` منتخب کریں۔ |
| `generate_audio` |  | boolean | no | `true` |  | ویڈیو کے ساتھ synchronized آڈیو شامل کرنے کے لیے اسے فعال کریں۔ تخلیق شدہ آڈیو میں lip movements سے ہم آہنگ speech، ماحولیاتی ambience اور sound effects شامل ہیں۔ |
| `bitrate_mode` |  | enum (string) | no | `standard` | `standard`, `high` | آؤٹ پٹ encoding bitrate منتخب کریں: 'standard' ڈیفالٹ برقرار رکھتا ہے، جبکہ 'high' بڑی فائل کے بدلے ماڈل سے encoding quality بہتر کرنے کو کہتا ہے۔ |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | ویڈیو codec کا انتخاب: `auto` ڈیفالٹ codec behavior برقرار رکھتا ہے، `H264` H.264 اور `H265` H.265 منتخب کرتا ہے۔ |

## 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.
