# Kling Video v2.6 Image to Video API

> v2.6-billede-til-video med valgfri slutframe, native lydgenerering og voice ID-referencer

Animerer et startbillede (`start_image_url`) med en prompt på højst 2500 tegn og kan slutte på et `end_image_url`. `duration` er 5 eller 10 sekunder. `generate_audio` producerer native lyd med kinesisk og engelsk tale, og `voice_ids` lader dig referere til op til 2 stemmer i prompten. En `negative_prompt` accepteres også.

- Model id: `kling-video/v2.6/pro/image-to-video`
- Made by: Kling
- Category: Image to Video
- Output: video
- Price: from $0.07 / second (5 s ≈ $0.35) (cheapest run $0.35 (350 API credits))
- Run: `POST https://api.doitong.ru/v1/run/kling-video/v2.6/pro/image-to-video`
- Quote: `POST https://api.doitong.ru/v1/quote/kling-video/v2.6/pro/image-to-video`
- Docs page: https://doitong.com/da/developers/models/kling-video/v2.6/pro/image-to-video

## Pricing

Price: **from $0.07 / second (5 s ≈ $0.35)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 10).

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

- When `generate_audio` = true and `voice_ids` is set: $0.168 (168 API credits) / second
- When `generate_audio` = true: $0.14 (140 API credits) / second

The full example input below costs $0.70 = 700 API credits (5 s × 140 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/v2.6/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

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `enable_safety_checker` |  | boolean | no | `true` |  | Sikkerhedstjek kan kun deaktiveres med kontogodkendelse; anmodninger uden godkendelse bliver altid kontrolleret. |
| `prompt` |  | string | yes |  | ≤ 2500 characters |  |
| `start_image_url` | `image` | string (image URL) | yes |  |  | URL, der peger på billedet brugt til videogenerering. Filstørrelsen må ikke overstige 50 MB; bredde og højde skal hver være mindst 300px, med et formatforhold mellem 0.40 og 2.50. |
| `duration` |  | enum (string) | no | `5` | `5`, `10` | Outputvideoens længde målt i sekunder. |
| `negative_prompt` |  | string | no | `blur, distort, and low quality` | ≤ 2500 characters |  |
| `generate_audio` |  | boolean | no | `true` |  | Skift til generering af indbygget videolyd, der understøtter stemmer på kinesisk eller engelsk og automatisk oversætter andre sprog til engelsk. Ved engelsk tale skal akronymer og egennavne skrives med store bogstaver og alt andet med små bogstaver. |
| `voice_ids` |  | array of string \| null | no |  |  | Valgfrie voice IDs brugt til at generere videoen, begrænset til 2 stemmer pr. opgave. Referer til dem i prompten med <<<voice_1>>> og <<<voice_2>>>. |
| `end_image_url` | `end_image` | string (image URL) \| null | no |  |  | URL, der peger på billedet ved videoens slutning. Filstørrelsen må ikke overstige 50 MB; bredde og højde skal hver være mindst 300px, med et formatforhold mellem 0.40 og 2.50. |

File parameters (`image`, `end_image`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## Example input

Required parameters only:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "start_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

## 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/v2.6/pro/image-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",
    "start_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }'

# 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/v2.6/pro/image-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",
    "start_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }),
});
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",
    "start_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/kling-video/v2.6/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/v2.6/pro/image-to-video",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "start_image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
      },
      "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.
