Authorizations

Authorization
string
header
required

##All endpoints require authentication using a Bearer Token##

Get your API Key:

Visit the API Key management page to obtain your API Key

Add it to the request header:

Authorization: Bearer YOUR_API_KEY

Body

application/json
model
enum<string>
required

Model name, fixed to gemini-omni-flash-video-edit

Available options:
gemini-omni-flash-video-edit
Example:

"gemini-omni-flash-video-edit"

prompt
string
required

Text prompt for video editing, describing the desired editing effect, supports both English and Chinese

Usage tips:

  • Describe the elements to change and the parts to keep unchanged (e.g. "make the lighting warmer and keep everything else unchanged")
  • Write negative requirements directly into the prompt (e.g. No dialogue, no text on screen); this model does not provide a separate negative prompt parameter
Example:

"Make the lighting in the scene warmer and keep everything else unchanged"

video_urls
string<uri>[]

Array of videos to edit; only 1 is supported

Input requirements:

  • Currently only HTTP/HTTPS video URLs are supported
  • Format: mp4
  • Duration: 3-10 seconds
Required array length: 1 element
Example:
["https://example.com/source.mp4"]
callback_url
string<uri>

HTTPS callback URL to notify when the task completes

Callback timing:

  • Triggered when the task completes (completed), fails (failed), or is cancelled (cancelled)
  • Sent after billing is confirmed

Security restrictions:

  • HTTPS protocol only
  • Callbacks to internal IP addresses are forbidden (127.0.0.1, 10.x.x.x, 172.16-31.x.x, 192.168.x.x, etc.)
  • URL length must not exceed 2048 characters

Callback mechanism:

  • Timeout: 10 seconds
  • Up to 3 retries on failure (retried 1s / 2s / 4s after each failure respectively)
  • The callback body format matches the response of the task query endpoint
  • A 2xx status code from the callback URL is treated as success; other status codes trigger a retry
Example:

"https://your-domain.com/webhooks/video-task-completed"
