}Kling V2.1 Text-to-Video is the latest-generation text-to-video model developed by the Kuaishou AI team. It can generate high-quality, cinematic short videos from input text with a single click. Compared with Kling 2.0, version 2.1 delivers major breakthroughs in motion fluidity, visual consistency, prompt understanding, and more.
This is an asynchronous API and only returns the task_id of the asynchronous task. You should use this task_id to request the Query Task Result API to retrieve the video generation result.
Request Headers
string
required
Enum value:
application/jsonstring
required
Bearer authentication format: Bearer {{API Key}}.
Request Body
string
required
The positive text prompt that guides generation. Maximum length: 2500 characters.
string
default:"5"
The duration of the generated video (in seconds).Available values:
5, 10string
default:"16:9"
The aspect ratio of the output video.Available values:
16:9, 9:16, 1:1number
The guidance strength parameter, which controls how closely the generated content matches the prompt.Value range: 0 to 1
Step: 0.1
Step: 0.1
string
The negative prompt, used to avoid undesired content. Maximum length: 2500 characters.
Response
string
required
The task_id of the asynchronous task. You should use this task_id to request the Query Task Result API to obtain the generation result
