Kling 3.0 Turbo API

Overview

Kling 3.0 Turbo is a fast Kuaishou video generation model on APIXO for short clips from text prompts or a single reference image. Use it when you want the Kling 3.0 family with a simpler surface than Kling 3.0 Std.

Capability	Value
Model ID	`kling-3-0-turbo`
Modes	`text-to-video`, `image-to-video`
Prompt	Required in both modes
Resolution	`720p`, `1080p`
Duration	`3-15` seconds
Aspect ratios	`16:9`, `9:16`, `1:1` for `text-to-video`
Reference images	`image-to-video`: exactly 1 image URL
Output	Video URLs in `resultJson.resultUrls`

Endpoint and authentication

Base URL:

https://api.apixo.ai/api/v1

Method	Endpoint	Purpose
`POST`	`/generateTask/kling-3-0-turbo`	Submit a generation task
`GET`	`/statusTask/kling-3-0-turbo?taskId={taskId}`	Poll task status and retrieve results

All requests require your APIXO API key:

Authorization: Bearer YOUR_API_KEY

Submit requests also require:

Content-Type: application/json

Copy-paste async quickstart

This minimal request submits a text-to-video task and returns a taskId.

curl -X POST "https://api.apixo.ai/api/v1/generateTask/kling-3-0-turbo" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "request_type": "async",
    "input": {
      "mode": "text-to-video",
      "prompt": "a cinematic city skyline at sunset with a slow push-in",
      "duration": 12,
      "resolution": "720p",
      "aspect_ratio": "16:9"
    }
  }'

Successful response:

{
  "code": 200,
  "message": "success",
  "data": {
    "taskId": "task_12345678"
  }
}

Save the taskId; you need it to poll for the final result.

Poll for result

curl -X GET "https://api.apixo.ai/api/v1/statusTask/kling-3-0-turbo?taskId=task_12345678" \
  -H "Authorization: Bearer YOUR_API_KEY"

Processing response:

{
  "code": 200,
  "message": "success",
  "data": {
    "taskId": "task_12345678",
    "state": "processing",
    "createTime": 1767965610929
  }
}

Success response:

{
  "code": 200,
  "message": "success",
  "data": {
    "taskId": "task_12345678",
    "state": "success",
    "resultJson": "{\"resultUrls\":[\"https://file.apixo.ai/video.mp4\"]}",
    "createTime": 1767965610929,
    "completeTime": 1767965652317,
    "costTime": 41388
  }
}

Failed response:

{
  "code": 200,
  "message": "success",
  "data": {
    "taskId": "task_12345678",
    "state": "failed",
    "failCode": "INVALID_PARAMETER",
    "failMsg": "One or more input parameters are invalid.",
    "createTime": 1767965610929,
    "completeTime": 1767965620132
  }
}

Parse resultJson after state becomes success:

const payload = JSON.parse(data.resultJson);
const videoUrls = payload.resultUrls;

Request body

Text-to-video

{
  "request_type": "async",
  "input": {
    "mode": "text-to-video",
    "prompt": "a cinematic city skyline at sunset with a slow push-in",
    "duration": 12,
    "resolution": "1080p",
    "aspect_ratio": "16:9"
  }
}

Image-to-video

{
  "request_type": "async",

    "mode": "image-to-video",
    "prompt": "animate the portrait with a gentle camera move",
    "duration": 15,

      "https://example.com/source.png"
    ]
  }
}

Parameters

string

default:"async"

required

Result delivery mode. Use async for polling with statusTask, or callback for webhook delivery.

string

Required when request_type is callback. Must be a public HTTPS URL that can receive the final task payload. See Webhooks.

object

required

Kling 3.0 Turbo input parameters.

Show properties

string

required

Generation mode. Supported values: text-to-video, image-to-video.

string

required

Text prompt describing the desired video. It must be a non-empty string in both modes.

integer

required

Output duration in seconds. Supports integer values or numeric strings from 3 to 15.

string

required

Output resolution. Supported values: 720p, 1080p.

string

default:"16:9"

Output aspect ratio for text-to-video only. Supported values: 16:9, 9:16, 1:1. If omitted in text-to-video, APIXO defaults to 16:9. This field is not forwarded for image-to-video.

string[]

Reference image URLs. Required for image-to-video. Provide exactly 1 non-empty image URL.

Response format

Submit task response

POST /generateTask/kling-3-0-turbo returns a task ID when the task is accepted:

integer

API status code. 200 means the task was accepted.

string

Human-readable status message.

string

Unique task identifier used with the status endpoint.

Status response fields

string

Unique task identifier.

string

Current task state: pending, processing, success, or failed.

string

JSON string containing the generated video URLs. Present when state is success.

string

Machine-readable failure code. Present when state is failed.

string

Human-readable failure message. Present when state is failed.

integer

Task creation timestamp in Unix milliseconds.

integer

Task completion timestamp in Unix milliseconds. Present after completion.

integer

Processing duration in milliseconds. Present after successful completion when available.

Webhook callback mode

Use callback mode when your backend should receive the final result automatically instead of polling.

curl -X POST "https://api.apixo.ai/api/v1/generateTask/kling-3-0-turbo" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "request_type": "callback",
    "callback_url": "https://your-server.com/webhooks/apixo",
    "input": {
      "mode": "image-to-video",
      "prompt": "animate the product photo with a slow camera move",
      "duration": 8,
      "resolution": "720p",
      "image_urls": [
        "https://example.com/product.png"
      ]
    }
  }'

The callback payload uses the same code, message, and data shape as the status response. See Webhooks for delivery requirements and retry behavior.

Billing

Kling 3.0 Turbo is billed per output second. text-to-video and image-to-video use the same pricing, and total cost is unit price * duration.

Resolution	Unit price	Example total
`720p`	`$0.112 / second`	12s: `$1.344`
`1080p`	`$0.14 / second`	15s: `$2.10`

For current route and market comparison pricing, see Pricing.

Latency and polling

Actual latency may vary by prompt complexity, selected resolution, route, and current queue load.

Request shape	Typical generation time	Recommended first poll	Poll interval
`3-5` second clip	60s-90s	60s after task creation	5s-10s
`6-10` second clip	90s-120s	60s after task creation	5s-10s
`11-15` second clip	120s-180s	60s after task creation	5s-10s

For production workloads, use callback mode to avoid frequent polling.

Rate limits and concurrency can vary by account, API key, and route. If you receive 429, slow down requests and retry with backoff. For account-level details, see System APIs.

Errors and troubleshooting

HTTP errors

Code	Meaning	What to do
`400`	Invalid request body, mode, parameter, or image URL	Fix the request before retrying
`401`	Missing or invalid API key	Check the `Authorization` header
`402`	Insufficient balance or quota	Add balance or switch account/key
`403`	Key or route cannot access the model	Check permissions and route strategy
`429`	Rate limit or concurrency limit reached	Retry with exponential backoff
`500`	Server error	Retry with backoff
`502`	Upstream service error	Retry with backoff
`504`	Upstream timeout	Retry or use callback mode for long-running jobs

Task failure codes

Fail code	Meaning	What to do
`CONTENT_VIOLATION`	Prompt or input media failed safety checks	Change the prompt or input image
`INVALID_PARAMETER`	A required field is missing or a value is unsupported	Check `mode`, `duration`, `resolution`, `aspect_ratio`, and `image_urls`
`INVALID_IMAGE_URL`	The reference image could not be fetched or decoded	Use a direct, publicly accessible image URL
`INSUFFICIENT_BALANCE`	The account does not have enough balance for the task	Add balance before retrying
`UPSTREAM_ERROR`	Upstream generation failed	Retry with backoff
`UNKNOWN_ERROR`	The failure could not be mapped to a more specific code	Retry later or contact support with the `taskId`

Common validation issues

Issue	Fix
Missing `mode`	Set `input.mode` to `text-to-video` or `image-to-video`
Missing `prompt`	Provide a non-empty prompt string
Unsupported `duration`	Use `3` through `15` seconds
Unsupported `resolution`	Use `720p` or `1080p`
Aspect ratio has no effect	`aspect_ratio` is only forwarded for `text-to-video`
`image-to-video` fails validation	Provide exactly 1 image URL in `image_urls`
