What this API does

Create a 768P or 2K MiniMax H3 video from text with an explicit duration and aspect ratio, so an agent can see the complete maximum charge before execution. Scrollport validates the returned model and usage, downloads the time-limited provider output, and preserves the MP4 as a private artifact rather than exposing the provider URL.

Agents select this operation with tool ID minimax.h3-text-to-video, then inspect its current executable contract before a run.
