Body

application/json

model · string · required

Model identifier in format provider/model

prompt · string · required

Text prompt describing the video to generate

input_reference · string

negative_prompt · string

Text describing what to avoid in the generated video

seed · integer

Seed for reproducible generation

video_uri · string

Source video URI for video-to-video generation (provider-specific, e.g. GCS URI)

audio · boolean

Enable audio generation in the video (supported by select providers/models)

fallbacks · object[]

object · enum<string>

Object type, always "video"

Available options: video

model · string

Model used for video generation

status · enum<string>

• completed: Video generation completed successfully
• failed: Video generation failed

Available options: queued, in_progress, completed, failed

progress · number<float>

Approximate completion percentage (0-100)

Required range: 0 <= x <= 100

prompt · string

Prompt used to generate the video

remixed_from_video_id · string

Source video ID if this is a remix

seconds · string

Duration of the generated video in seconds as a string (e.g., "4")

size · string

created_at · integer<int64>

Unix timestamp (seconds) when the job was created

completed_at · integer<int64>
