# Kling 3.0 Pro Image to Video API

> Menganimasikan imej pegun menjadi klip 3 hingga 15 saat dengan bunyi natif, bingkai akhir pilihan dan prompt berbilang syot.

Model imej-ke-video unggulan Kling mengekalkan subjek imej mula sambil menambah gerakan semula jadi, pergerakan kamera dan, secara lalai, bunyi serta pertuturan yang sepadan. Berikan imej akhir untuk mengawal tempat syot berakhir, pecahkan satu penjanaan kepada beberapa syot dengan prompt setiap syot, atau tetapkan watak dan objek berulang dengan elemen rujukan. Bentuk bingkai mengikut imej mula.

- Model id: `kling-video/v3/pro/image-to-video`
- Made by: Kling
- Category: Image to Video
- Output: video
- Price: from $0.112 / second (5 s ≈ $0.56) (cheapest run $0.56 (560 API credits))
- Run: `POST https://api.doitong.ru/v1/run/kling-video/v3/pro/image-to-video`
- Quote: `POST https://api.doitong.ru/v1/quote/kling-video/v3/pro/image-to-video`
- Docs page: https://doitong.com/ms/developers/models/kling-video/v3/pro/image-to-video

## Pricing

Price: **from $0.112 / second (5 s ≈ $0.56)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 5).

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

- When `generate_audio` = true and `elements` is set: $0.196 (196 API credits) / second
- When `generate_audio` = true: $0.168 (168 API credits) / second

The full example input below costs $0.84 = 840 API credits (5 s × 168 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/kling-video/v3/pro/image-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
{
  "image": "https://content.doitong.com/images/gp/image_20260610003801_541d9719_316882.png"
}
```

A fuller example:

```json
{
  "prompt": "The banana manager turns to the camera, smiles and waves while coworkers keep typing, gentle handheld camera",
  "image": "https://content.doitong.com/images/gp/image_20260610003801_541d9719_316882.png",
  "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/kling-video/v3/pro/image-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "The banana manager turns to the camera, smiles and waves while coworkers keep typing, gentle handheld camera",
    "image": "https://content.doitong.com/images/gp/image_20260610003801_541d9719_316882.png",
    "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
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/kling-video/v3/pro/image-to-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "The banana manager turns to the camera, smiles and waves while coworkers keep typing, gentle handheld camera",
    "image": "https://content.doitong.com/images/gp/image_20260610003801_541d9719_316882.png",
    "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": "The banana manager turns to the camera, smiles and waves while coworkers keep typing, gentle handheld camera",
    "image": "https://content.doitong.com/images/gp/image_20260610003801_541d9719_316882.png",
    "duration": 5,
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/kling-video/v3/pro/image-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": "kling-video/v3/pro/image-to-video",
      "input": {
        "prompt": "The banana manager turns to the camera, smiles and waves while coworkers keep typing, gentle handheld camera",
        "image": "https://content.doitong.com/images/gp/image_20260610003801_541d9719_316882.png",
        "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.
