# Seedance 2.5 US Text to Video API

> Seedance 2.5 ya maandishi-hadi-video yenye klipu hadi sekunde 30 na tokeo hadi 1080p

Huzalisha video kutoka kwa kidokezo cha maandishi ikiwa na sauti iliyosawazishwa kwa chaguomsingi. Mwonekano unaweza kuwa 480p, 720p au 1080p, na muda ni auto au sekunde 4 hadi 30. Uwiano wa vipimo ni kutoka 21:9 hadi 9:16 au auto. `bitrate_mode` hutoa standard au high, na kodeki inaweza kuwa H264 au H265.

- Model id: `bytedance/seedance-2.5/us/text-to-video`
- Made by: ByteDance
- Category: Text to Video
- Output: video
- Charged by usage (up to $6.944 per run; the rest of the hold is refunded): $0.0107 / 1000 tokens (cheapest run $0.416 (416 API credits))
- Run: `POST https://api.doitong.ru/v1/run/bytedance/seedance-2.5/us/text-to-video`

## Pricing

Price: **$0.0107 / 1000 tokens**. Charged by actual usage at $0.0107 / 1000 tokens: up to $6.944 per run (the quote gives the maximum for your input), the rest is refunded automatically after the run.

The full example input below holds up to $6.944 = 6944 API credits (up to 648.9 × 1000 tokens × $0.0107) when it starts.

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). This model is charged by usage: `POST https://api.doitong.ru/v1/quote/bytedance/seedance-2.5/us/text-to-video` with the same JSON body returns the most the run can cost for that input (`credits`, debited when the run starts); after the run you pay the usage the model reports and the rest is refunded automatically. An input whose maximum would exceed the per-run limit is refused with 422. 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 |  |  | Kidokezo cha maandishi kinachoelekeza uzalishaji wa video. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p`, `1080p` | Mwonekano wa tokeo: 480p hupendelea kasi, 720p hutoa uwiano, na 1080p hutoa ubora wa juu. |
| `duration` |  | enum (string) | no | `auto` | `auto`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15`, `16`, `17`, `18`, `19`, `20`, `21`, `22`, `23`, `24`, `25`, `26`, `27`, `28`, `29`, `30` | Uteuzi wa urefu wa video: `auto` hukabidhi chaguo kwa modeli kwa kutumia kidokezo, huku muda ulioainishwa lazima uwe kati ya sekunde 4 hadi 30. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Uwiano wa picha wa tokeo: 16:9 hutoa mlalo, 9:16 hutoa picha wima, 1:1 hutoa mraba, na 21:9 hutoa mwonekano mpana wa sinema. Chagua `auto` ili modeli ichague uwiano. |
| `generate_audio` |  | boolean | no | `true` |  | Washa hii ili video iambatane na sauti iliyosawazishwa. Sauti iliyozalishwa inajumuisha usemi unaolingana na miondoko ya midomo, mandhari ya mazingira na athari za sauti. |
| `bitrate_mode` |  | enum (string) | no | `standard` | `standard`, `high` | Chagua kiwango cha biti cha usimbaji wa tokeo: 'standard' huhifadhi chaguo chaguomsingi, ilhali 'high' huiomba modeli kuboresha ubora wa usimbaji kwa gharama ya faili kubwa zaidi. |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | Uteuzi wa kodeki ya video: `auto` huacha tabia ya kodeki chaguomsingi bila kubadilika, `H264` huchagua H.264, na `H265` huchagua H.265. |
| `end_user_id` |  | string \| null | no |  |  | Kitambulisho cha kipekee alichopewa mtumiaji wa mwisho. |

## Example input

Required parameters only:

```json

  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## 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-2.5/us/text-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

# 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-2.5/us/text-to-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
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 red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/bytedance/seedance-2.5/us/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-2.5/us/text-to-video",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.
