Description: Copyable MiniMax native API requests for H3 and H3 Max video generation, media references, Context, and 2K regeneration.

Agent guidance:
- Use this page when the user is asking about this specific route or model capability.
- Preserve endpoint paths, JSON keys, model IDs, and placeholder values exactly.
- `{BASE_URL}` means `https://api.uniall.ai`; treat `sk-***` and `task_xxx` as safe placeholders, not real secrets.
