This is the machine-readable API reference for **Kling Video O3 Std Video-Edit** on Atlas Cloud,
a unified API platform for 400+ AI models across text, image, video, audio and 3D.

- **Model ID**: `kwaivgi/kling-video-o3-std/video-edit`
- **Built by**: Kuaishou
- **Modality**: Video
- **Model page**: https://www.atlascloud.ai/models/kwaivgi/kling-video-o3-std/video-edit
- **API key**: https://www.atlascloud.ai/console/api-keys
- **Docs**: https://www.atlascloud.ai/docs

## Pricing on Atlas Cloud

- $0.107 per second of generated video
- Pay-as-you-go. No minimum spend, no subscription required.

> **These are the authoritative Atlas Cloud rates for this model.** Any price that
> appears in the vendor description further down refers to a different platform or
> a different model variant and does not apply here.

## Use this model from an AI agent

Atlas Cloud ships three first-party integration surfaces. All three authenticate
with the same API key via the `ATLASCLOUD_API_KEY` environment variable.

### MCP server

The official MCP server (`atlascloud-mcp`) exposes this model to any
MCP-compatible host — Claude Code, OpenAI Codex, Cursor, Gemini CLI, Goose,
Claude Desktop. One-line install:

```bash
# Claude Code
claude mcp add atlascloud -- npx -y atlascloud-mcp

# OpenAI Codex CLI
codex mcp add atlascloud -- npx -y atlascloud-mcp

# Gemini CLI
gemini mcp add atlascloud -- npx -y atlascloud-mcp

export ATLASCLOUD_API_KEY="your-api-key"
```

Then ask in plain English; the agent calls `atlas_generate_video` with `model: "kwaivgi/kling-video-o3-std/video-edit"`.
The server fetches each model's schema and validates parameters before submitting,
so invalid requests fail fast without spending credits.

### Agent Skills

`atlas-cloud-skills` is a portable skill package (API reference, code templates in
Python / Node.js / cURL, model IDs with pricing) for Claude Code, Cursor, Codex and
12+ other agents:

```bash
npx skills add AtlasCloudAI/atlas-cloud-skills
export ATLASCLOUD_API_KEY="your-api-key"
```

Skills docs: https://www.atlascloud.ai/docs/skills

### CLI

The `atlas` binary runs Atlas Cloud from a terminal or CI script. Async media jobs
are polled and downloaded automatically (use `--no-download` when a script only
needs the output URLs):

```bash
# Install (Homebrew, npm, or shell installer)
brew install AtlasCloudAI/tap/atlascloud
# npm install -g atlascloud-cli
# curl -fsSL https://raw.githubusercontent.com/AtlasCloudAI/cli/main/install.sh | sh

atlas auth login
atlas generate video kwaivgi/kling-video-o3-std/video-edit -p "Your prompt here"
```

## HTTP API reference

- **Submit endpoint (POST)**: `https://api.atlascloud.ai/api/v1/model/generateVideo` — start an async generation; returns a `prediction_id`
- **Poll endpoint (GET)**: `https://api.atlascloud.ai/api/v1/model/prediction/{prediction_id}` — poll this until the prediction finishes
- **Model ID**: `kwaivgi/kling-video-o3-std/video-edit`

  The video URL. Video duration can not be longer than 10s.

- **`images`** (`array[string]`, _optional_):
  Including reference images of the element, scene, style, etc. Max 4
  - Max items: 4

- **`keep_original_sound`** (`boolean`, _optional_):
  Whether to keep the original sound from the video.
  - Default: `true`



**Required Parameters Example**:

```json
{
  "model": "kwaivgi/kling-video-o3-std/video-edit",
  "prompt": "",
  "video": ""
}
```


**Full Example**:

```json
{
  "model": "kwaivgi/kling-video-o3-std/video-edit",

  "images": [
    ""
  ],
  "keep_original_sound": true
}
```


### Output Schema

The API returns the following output format:


- **`created_at`** (`string`, _optional_):
  ISO timestamp of when the request was created.

- **`id`** (`string`, _optional_):
  Unique identifier for the prediction, the ID of the prediction to get.

- **`model`** (`string`, _optional_):
  Model ID used for the prediction.

- **`outputs`** (`array[string]`, _optional_):
  Array of URLs to the generated content (empty when status is not completed).

- **`status`** (`string`, _optional_):
  Status of the task: created, processing, completed, or failed.

- **`urls`** (`object`, _optional_):
  Object containing related API endpoints.



**Example Response**:

```json
{
  "created_at": "",
  "id": "",
  "model": "",
  "outputs": [
    ""
  ],
  "status": "",
  "urls": {}
}
```


## Usage Examples

### cURL

```bash
# Step 1: Start generation (async)
curl -X POST "https://api.atlascloud.ai/api/v1/model/generateVideo" \
  -H "Authorization: Bearer $ATLASCLOUD_API_KEY" \

# Response will contain: {"code": 200, "data": {"id": "prediction_id", "status": "processing"}}

# Step 2: Poll for result (replace {prediction_id} with the id returned above)
curl -X GET "https://api.atlascloud.ai/api/v1/model/prediction/{prediction_id}" \
  -H "Authorization: Bearer $ATLASCLOUD_API_KEY"

# Keep polling until status is "completed", "succeeded" or "failed"
# When completed, outputs will contain the generated content URL(s)

## About this model

_Vendor-supplied description. Any pricing or endpoint mentioned below refers to_
_other platforms — use the Atlas Cloud values above._

#### Kling Video O3 Std Video Edit

Kling Video O3 Standard Video Edit uses Kuaishou's Kling 3.0 Omni model in Standard mode (720P output) to edit existing footage with natural language. You can add, remove or replace objects, swap backgrounds, change shot composition, angle, style, color, weather or lighting, all with strong temporal consistency. The output keeps the duration of the input video.

#### Why Choose This?

- **Prompt-driven editing** Describe the change in plain language. No masks, timeline or keyframes are needed.
- **Reference image support** Attach up to 4 reference images to define the new element, scene or style.
- **Audio preservation** Keep the original soundtrack with `keep_original_sound`.
- **Scene-level understanding** The model recognizes objects, backgrounds and context, so edits fit the scene.
- **Motion-consistent output** Edits blend naturally across frames with minimal flicker or ghosting.

#### Parameters

| Parameter | Required | Description |
| --- | --- | --- |
| prompt | Yes | Description of the edit. Max 2,500 characters. Refer to inputs with `<<<video_1>>>` and `<<<image_1>>>`, `<<<image_2>>>`, …, e.g. `Put the crown from <<<image_1>>> on the girl in blue in <<<video_1>>>.` |
| video | Yes | Video to edit (URL or upload). MP4 / MOV, 3–10 s long, width and height 700–4553 px, 24–60 fps (output is 24 fps), up to 200 MB, aspect ratio between 1:2.5 and 2.5:1. |
| images | No | Up to 4 reference images of the target element, scene or style. JPG / JPEG / PNG, up to 10 MB each, at least 300 px on each side, aspect ratio between 1:2.5 and 2.5:1. |
| keep_original_sound | No | Keep the original audio of the input video (default: `true`). |

The output keeps the duration and aspect ratio of the input video, so there are no `duration` or `aspect_ratio` parameters. Output resolution is 720P for Standard mode.
