Kling

Kling 3.0 Omni

Kling 3.0 Omni video. Drive generation with a prompt plus any combination of a first frame, a first+last frame pair, reference images and one reference video.

Referring to materials in the prompt — every material gets an index you can mention with @: images are numbered @image_1… in the order first frame → last frame → ref_imgs, and the reference video is always @video_1. The array order is the numbering, so reordering ref_imgs changes what your prompt refers to.

Reference video roles (video_type):

feature (default) — the output imitates its motion and style. Upstream forces multi-shot on and audio off for this mode, so generate_audio is rejected here.
base — the video is edited in place. First / last frames and multi_shots are not supported, and generate_audio keeps the base video’s original sound rather than generating a new track.

Material limits — image_url + image_end_url + ref_imgs must not exceed 7 in total, or 4 when ref_videos is used.

Pricing — per second of generated video, in tokens (USD at $0.02/token). Same as the official rate:

scenario	720p	1080p	4k
No video · no audio	4.2 ($0.084)	5.6 ($0.112)	21 ($0.42)
No video · native audio	5.6 ($0.112)	7 ($0.14)	21 ($0.42)
With video	6.3 ($0.126)	8.4 ($0.168)	21 ($0.42)

⚠️ Pricing is three-dimensional — resolution × reference video × native audio. A request with a reference video costs 50% more than a plain one at the same resolution, so do not read this as a two-tier table.

⚠️ At 4K all three scenarios cost the same (21 tokens/s). That is the official rate, not a typo here.

⚠️ There is no “with video + native audio” price because the combination does not exist: feature forbids audio, and base’s audio is retained rather than generated — both are billed at the “with video” tier.

Not the same model as kling-o1. O1 shares the upstream path prefix but drops multi-shot, 4K and generated audio, and caps duration at 10s.

Returns an img_uuid; poll GET /api/v1/jobs/detail (or use custom_callback_url) to get the generated video.

Reference materials use the shared naming: ref_imgs and ref_videos, the same as seedance / hailuo / wan’s reference endpoints. ref_videos is an array capped at 1. The older image_urls / video_url spellings still work.

⚠️ Do not confuse image_url (first frame) with ref_imgs (reference images) — they are different inputs and count against the same material budget.

Headers

Authorization

string

Body

application/json

model

enum<string>

required

Model name. Must be kling-v3-omni.

Available options:

kling-v3-omni

prompt

string

required

Text prompt. Use @image_1 / @video_1 to refer to specific materials.

image_url

string<uri>

Optional. First-frame image URL.

image_end_url

string<uri>

Optional. Last-frame image URL. Requires image_url — last-frame-only is not supported.

ref_imgs

string<uri>[]

Optional reference images. Order is the @image_N numbering. image_urls is accepted as a compatible alias.

Maximum array length: 7

ref_videos

string<uri>[]

Optional reference video (.mp4 / .mov, 3–15.5s). At most one. Named as an array to match the other reference-driven endpoints (ref_imgs / ref_videos / ref_audios), even though only one is allowed. video_url is accepted as a compatible alias, and a bare string is accepted too.

Maximum array length: 1

video_type

enum<string>

default:feature

Role of video_url. See the description above. Requires ref_videos.

Available options:

feature,

base

duration

integer

default:5

Video duration in seconds. Any integer from 3 to 15.

Required range: 3 <= x <= 15

resolution

enum<string>

default:720p

Output resolution. quality is accepted as a compatible alias.

Available options:

720p,

1080p,

4k

ratio

enum<string>

default:16:9

Output aspect ratio. Only used when there is no first frame and no reference video — otherwise the material decides. aspect_ratio is accepted as a compatible alias.

Available options:

16:9,

9:16,

1:1

generate_audio

boolean

default:false

Generate a native audio track. ⚠️ Rejected together with video_type: feature. Costs more per second when there is no reference video.

multi_shots

boolean

default:false

Generate a multi-shot video. ⚠️ Rejected together with video_type: base. Note the upstream default is true; GoEnhance always sends this explicitly so an omitted value means single-shot.

custom_callback_url

string<uri>

Optional. A publicly accessible HTTPS URL. When the task status changes (processing / success / failed), GoEnhance sends a POST request to this URL. The request body is identical to the response of GET /api/v1/jobs/detail. If your server does not respond with HTTP 200, the notification is retried up to 3 times, with a 3-second timeout per attempt.

Example:

"https://your-server.com/goenhance/callback"
