API README

MiniMax H3 Video Regeneration

Regenerate one base video as a 2K MiniMax H3 video using a required text prompt. Upload exactly one video; SandBase securely assembles the request with the video as base_video.

Example request fields:

{
  "prompt": "Enhance the scene with cinematic lighting",
  "videos": ["https://static.sandbase.ai/examples/pixverse/sound-effects/input_video_0.mp4"],
  "resolution": "2K",
  "aigc_watermark": false
}

The $0.65 base price is a catalog reference for 5 output seconds with no chargeable input material. Final billing never falls back to the base price: it uses completed-task usage at $0.13 per output second and $0.08 per input-video second, plus $0.04 for each input image after the first 5. Reference audio is free. If any required usage value is unavailable or invalid, settlement remains pending for retry or reconciliation.
