Async processing mode, returns task ID for subsequent queries
Supports text-to-video, image-to-video, explicit first/last frame control, and audio video
Supports standard mode (720P) and professional mode (1080P)
Professional mode supports automatic audio generation

Authorization

string

required

All API endpoints require Bearer Token authentication.

Authorization: Bearer YOUR_API_KEY

Request Parameters

string

required

Video generation model name, fixed as kling-v2-6.

string

required

Text prompt, maximum 2500 characters.

string

default:"std"

Generation mode.

std - standard mode (720P, silent video only)
pro - professional mode (1080P, supports automatic audio generation)

integer

default:"5"

Video duration in seconds.Options: 5 or 10

string

default:"16:9"

Video aspect ratio. Common values: 16:9, 9:16, 1:1

string[]

Normal reference images.

These images are treated as references only
They are not automatically converted into first/last frames
Use image_with_roles for explicit frame control

object[]

Explicit image-role array for frame control and mixed inputs.

Show Show image_with_roles object fields

string

required

Publicly accessible image URL.

string

required

Image role.Supported values:

first_frame
last_frame
reference
reference_image

last_frame is only sent when explicitly declared in image_with_roles. The system no longer infers the last frame from reference_images[1].

string

Negative prompt to exclude unwanted content.

boolean

default:"false"

Whether to automatically generate audio.

Available only in mode: "pro".

boolean

Whether to add watermark.

Input Rules

Input shape	Behavior
`reference_images` only	Normal references
`image_with_roles` with only `first_frame` / `last_frame`	Frame control
Both fields used together, or roles include both frame and reference semantics	Mixed mode
