Minimax Tools

Direct MiniMax API integration for speech synthesis (TTS), voice cloning, image generation, video generation, and music generation using local Python scripts instead of MCP. Use when you want reliable script-based MiniMax workflows inside OpenClaw for: (1) text-to-speech with built-in Chinese/English defaults or explicit voice IDs, (2) voice cloning with upload + preview flows, (3) text-to-image or reference-image generation, (4) text-to-video, image-to-video, or first/last-frame video generation with async polling/download, and (5) music generation from prompts and lyrics.

Use this skill to call MiniMax multimodal APIs directly through local Python wrappers instead of relying on an external MCP server.

Overview

This skill currently supports:

• Speech synthesis (TTS)
• Voice cloning
• Image generation
• Video generation
• Music generation

All wrappers are exposed through a single entrypoint script:

bash

python3 scripts/minimax.py <subcommand> ...

Read references/api-notes.md only when you need endpoint details or parameter reminders.

Prerequisites

Expect these environment variables to be available before running the scripts:

• MINIMAX_API_KEY

Optional:

• MINIMAX_BASE_URL if you need to override the default API host

Python dependency:

• requests

Routing guide

• Use tts for speech synthesis
• Use voice for uploading clone inputs, creating cloned voices, and optionally downloading preview audio
• Use image for text-to-image or reference-image generation
• Use video for text-to-video, image-to-video, or first/last-frame video workflows
• Use music for song or instrumental generation

TTS defaults

• Default model: speech-2.8-turbo
• Default format: mp3
• Default sample rate: 32000
• Default bitrate: 128000
• Default Chinese voice: Chinese (Mandarin)_Lyrical_Voice
• Default English voice: English_Graceful_Lady
• If --voice is omitted, the script uses --voice-lang zh|en and defaults to zh

Voice cloning notes

• Clone source audio constraints:
  • mp3, m4a, or wav
  • 10 seconds to 5 minutes
  • <= 20 MB
• Optional prompt audio constraints:
  • mp3, m4a, or wav
  • under 8 seconds
  • <= 20 MB
• If cloning succeeds, the returned voice_id can be used immediately in TTS
• MiniMax documentation notes cloned voices are temporary unless used in real TTS within 7 days

Video support

Supported modes:

• text-to-video: video create
• image-to-video: video i2v
• first/last-frame video: video fl2v

Video creation is asynchronous. Use video query, video wait, and video download for task follow-up.

File handling rules

• Prefer saving outputs locally and returning file paths
• Local image inputs for image/video wrappers can be converted to Data URLs automatically
• Prefer URL-based output when MiniMax returns temporary files, then download immediately
• Avoid tight polling loops for async video jobs
