How to Make a Call
Step-by-Step Instructions
Generating a video using this model involves sequentially calling two endpoints:
The first one is for creating and sending a video generation task to the server (returns a generation ID).
The second one is for requesting the generated video from the server using the generation ID received from the first endpoint.
Below, you can find both corresponding API schemas.
API Schemas
Create a video generation task and send it to the server
This endpoint creates and sends a video generation task to the server — and returns its ID.
post
Body
modelstring · enumRequiredPossible values:
promptstringOptional
Text prompt for video generation. Either prompt or multi_prompt must be provided, but not both.
multi_promptstring[]Optional
List of prompts for multi-shot video generation. If provided, overrides the single prompt and divides the video into multiple shots with specified prompts and durations.
aspect_ratiostring · enumOptional
The aspect ratio of the generated video.
Default: 16:9Possible values:
durationinteger · enumOptional
The length of the output video in seconds.
Default: 5Possible values:
shot_typestring · enumOptional
The type of multi-shot video generation
Default: customizePossible values:
generate_audiobooleanOptional
Whether to generate audio for the video.
Default: true
negative_promptstringOptional
The description of elements to avoid in the generated video.
cfg_scalenumber · max: 1Optional
The CFG (Classifier Free Guidance) scale is a measure of how close you want the model to stick to your prompt.
Responses
200Success
application/json
idstringRequired
The ID of the generated video.
Example: 60ac7c34-3224-4b14-8e7d-0aa0db708325
statusstring · enumRequired
The current status of the generation task.
Example: completedPossible values:
post
/v2/video/generations
200Success
Retrieve the generated video from the server
After sending a request for video generation, this task is added to the queue. This endpoint lets you check the status of a video generation task using its id, obtained from the endpoint described above.
If the video generation task status is completed, the response will include the final result — with the generated video URL and additional metadata.
