POST
  1. After submission, a task_id will be returned. If you provided a callback_url, Vidgo sends a POST request when the task becomes finished or failed.
  2. You can always retrieve the result through the unified Query Task Status endpoint.

​
Available Models

  • kling-1.6/standard - Cost-effective Kling 1.6 video generation at 9 credits per second.
  • kling-1.6/pro - Higher-quality Kling 1.6 video generation at 15 credits per second.

​
Input Routing

Vidgo does not require a public mode, type, or task_type field for Kling 1.6. All Kling 1.6 requests require prompt and duration.
  • Provide no image fields to generate text-to-video.
  • Provide start_image_url to generate image-to-video.
  • Provide start_image_url and end_image_url with kling-1.6/pro to control both the first and last frame.
  • Provide image_urls with 1 to 4 reference images to generate Elements.
image_urls cannot be used together with start_image_url, end_image_url, or cfg_scale.

​
Parameter Compatibility

Notes:
  • end_image_url requires start_image_url and is only supported by kling-1.6/pro.
  • kling-1.6/standard image-to-video does not support aspect_ratio.
  • Elements supports 1 to 4 image_urls and does not support cfg_scale.
  • prompt and negative_prompt support up to 2500 characters.
  • cfg_scale must be between 0 and 1 when provided.

​
Response and Status

The submit endpoint returns a Vidgo task_id. Use it with the unified Query Task Status endpoint to retrieve the final video URL. Initial submit responses include status, which is usually running after the upstream video task has been created. If submission fails during upstream task creation, the status may be failed and the task can be inspected through the status endpoint.

​
Pricing

  • kling-1.6/standard: 9 credits per second.
