# Seedance 2.5 API

> Completes a saved Seedance 2.5 draft by regenerating it at 1080p from its draft id

Takes a `draft_id` from an earlier Seedance 2.5 draft run and renders the final video. The id stays valid for seven days and only for the original caller. Output is fixed at 1080p, and the codec can be auto, H264 or H265. It returns the video and seed.

- Model id: `bytedance/seedance-2.5/draft/complete`
- Made by: ByteDance
- Category: Video to Video
- Output: video
- Estimated price per run: $9.15 / run (cheapest run $9.15 (9150 API credits))
- Run: `POST https://api.doitong.com/v1/run/bytedance/seedance-2.5/draft/complete`
- Quote: `POST https://api.doitong.com/v1/quote/bytedance/seedance-2.5/draft/complete`
- Docs page: https://doitong.com/developers/models/bytedance/seedance-2.5/draft/complete

## Pricing

Price: **$9.15 / run**. Estimated from the typical cost of one run. The quote is exactly what the run charges.

The full example input below costs $9.15 = 9150 API credits (1 request × 9150 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.com/v1/quote/bytedance/seedance-2.5/draft/complete` 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 |
|---|---|---|---|---|---|---|
| `draft_id` |  | string | yes |  | 1 – 8192 characters | Draft identifier (`draft_id`) from a draft-enabled response, usable exclusively by the original caller during its seven-day validity period. |
| `resolution` |  | string | no | `1080p` |  | Output resolution for completed drafts is restricted to 1080p. |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | Video codec selection: `auto` leaves the default codec behavior unchanged, `H264` selects H.264, and `H265` selects H.265. |

## Example input

Required parameters only:

```json
{
  "draft_id": "your-draft-id"
}
```

A fuller example:

```json
{
  "draft_id": "your-draft-id"
}
```

## 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/bytedance/seedance-2.5/draft/complete?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "draft_id": "your-draft-id"
  }'

# 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/bytedance/seedance-2.5/draft/complete?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "draft_id": "your-draft-id"
  }),
});
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 = {
    "draft_id": "your-draft-id",
}

# 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/draft/complete", 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": "bytedance/seedance-2.5/draft/complete",
      "input": {
        "draft_id": "your-draft-id"
      },
      "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.
