## Pricing

Price: **from $0.141 / second (4 s ≈ $0.564)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 15).

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `video_urls` is set and `duration` ≤ 4: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second
- When `video_urls` is set and `duration` ≤ 5: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second
- When `video_urls` is set and `duration` ≤ 6: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second
- When `video_urls` is set and `duration` ≤ 7: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second
- When `video_urls` is set and `duration` ≤ 8: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second
- When `video_urls` is set and `duration` ≤ 9: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second
- When `video_urls` is set and `duration` ≤ 10: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second
- When `video_urls` is set and `duration` ≤ 11: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second
- When `video_urls` is set and `duration` ≤ 12: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second
- When `video_urls` is set and `duration` ≤ 13: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second
- When `video_urls` is set and `duration` ≤ 14: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second
- When `video_urls` is set: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second
- When `resolution` is 480p, 720p, 1080p, 4k: by `resolution`, 480p: $0.141, 720p: $0.304, 1080p: $0.682, 4k: $1.556 / second

The full example input below costs $1.52 = 1520 API credits (5 s × 304 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/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

## Example input

Required parameters only:

```json
{
  "prompt": "@Image1 The banana manager walks through the office and high-fives the carrot, upbeat comedy tone"
}
```

A fuller example:

```json
{
  "prompt": "@Image1 The banana manager walks through the office and high-fives the carrot, upbeat comedy tone",
  "images": [
    "https://content.doitong.com/images/gp/image_20260610003801_541d9719_316882.png"
  ],
  "resolution": "720p",
  "duration": 5
}
```

## 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/reference-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "@Image1 The banana manager walks through the office and high-fives the carrot, upbeat comedy tone",
    "images": [
      "https://content.doitong.com/images/gp/image_20260610003801_541d9719_316882.png"
    ],
    "resolution": "720p",
    "duration": 5
  }'

# 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

    ],
    "resolution": "720p",
    "duration": 5
  }),
});
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": "@Image1 The banana manager walks through the office and high-fives the carrot, upbeat comedy tone",
    "images": [

    ],
    "resolution": "720p",
    "duration": 5,
}

# Run the model; wait up to 20 s for the finished result in the same call

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/reference-to-video",
      "input": {
        "prompt": "@Image1 The banana manager walks through the office and high-fives the carrot, upbeat comedy tone",
        "images": [
          "https://content.doitong.com/images/gp/image_20260610003801_541d9719_316882.png"
        ],
        "resolution": "720p",
        "duration": 5
      },
      "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.
