# Kling O1 Image API

> Uhariri wa picha unaoongozwa na marejeleo wenye hadi picha 10, tagi za @Image na elements, 1K au 2K, na hadi matokeo 9

Huhariri au kuchanganya upya picha kutoka kwenye `prompt` yenye hadi herufi 2500. Elekeza kwenye ingizo kwa @Image1, @Image2 na kadhalika, ukitumia hadi 10 katika `image_urls`; `elements` huongeza wahusika au vitu, ikiwa na jumla ya juu ya 10. `resolution` ni 1K au 2K, `num_images` ni 1 hadi 9, na `aspect_ratio` inajumuisha auto, 21:9 na 3:2. Matokeo ni png, jpeg au webp.

- Model id: `kling-image/o1`
- Made by: Kling
- Category: Image Editing
- Output: image
- Price: $0.028 / image (cheapest run $0.028 (28 API credits))
- Run: `POST https://api.doitong.com/v1/run/kling-image/o1`
- Quote: `POST https://api.doitong.com/v1/quote/kling-image/o1`
- Docs page: https://doitong.com/sw/developers/models/kling-image/o1

## Pricing

Price: **$0.028 / image**. Billed per generated image (`num_images`, default 1).

The full example input below costs $0.028 = 28 API credits (1 image × 28 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/kling-image/o1` 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 |

| `prompt` |  | string | yes |  | ≤ 2500 characters | Kidokezo cha uzalishaji wa picha chenye kikomo cha vibambo 2500. Rejelea picha kwa @Image1, @Image2, na kuendelea, au @Image kwa picha moja. |
| `image_urls` | `images` | array of image URL | yes |  |  | Orodha ya picha za marejeo, yenye kikomo cha picha 10; zitaje kwenye kidokezo kama @Image1, @Image2, na kuendelea, huku nambari zikianzia 1.

| `elements[].frontal_image_url` |  | string (image URL) \| null | no |  |  | Picha ya hiari inayoangalia mbele na kutoa mwonekano mkuu wa kipengele. Ukubwa wa faili hauwezi kuzidi 10.0 MB; upana na urefu lazima kila moja iwe angalau 300px, na uwiano wa picha uwe kutoka 0.40 hadi 2.50. |
| `elements[].reference_image_urls` |  | array of image URL \| null | no |  |  | Seti ya hiari ya picha 0–3 za ziada zinazoonyesha pembe nyingine. Kila faili lazima isiwe kubwa kuliko 10.0 MB, upana na urefu kila moja uwe angalau 300px, na uwiano wa picha uwe kutoka 0.40 hadi 2.50. |
| `resolution` |  | enum (string) | no | `1K` | `1K`, `2K` | Mwonekano wa picha ya tokeo: 1K kwa mwonekano wa kawaida au 2K kwa mwonekano wa juu. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 9 | Idadi ya picha za tokeo, kutoka 1 hadi 9. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `16:9`, `9:16`, `1:1`, `4:3`, `3:4`, `3:2`, `2:3`, `21:9` | Uwiano wa picha iliyozalishwa, unaochaguliwa kiotomatiki kutoka kwenye maudhui ya ingizo ukiwekwa kuwa 'auto'. |

| `enable_safety_checker` |  | boolean | no | `true` |  | Ukaguzi unaweza kulegezwa kwa kuweka false, ikiwa mpigaji simu ameidhinishwa. |

File parameters (`images`) 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",
  "images": [
    "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",
  "image_urls": [
    "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.com/v1/run/kling-image/o1?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",
    "image_urls": [
      "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.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/kling-image/o1?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",
    "image_urls": [
      "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.com/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",
    "image_urls": [
        "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-image/o1", 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": "kling-image/o1",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "image_urls": [
          "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.
