MiniMax Multimodal Toolkit#

Generate voice, music, image, and video content via MiniMax APIs. Pure Python — works on Windows, Mac, and Linux without any third-party dependencies.

Prerequisites#

• MINIMAX_API_KEY environment variable (starts with sk-)
• MINIMAX_API_HOST environment variable (optional, default: https://api.minimaxi.com)
• Python 3.6+
• For video duration detection: ffprobe (optional)

Quick Start#

bash

# Load the Python module
import sys; sys.path.insert(0, "{skillDir}/scripts"); import minimax_api

Or use CLI directly:

bash

python "{skillDir}/scripts/minimax_api.py" tts "Hello world" -o minimax-output/hello.mp3
python "{skillDir}/scripts/minimax_api.py" image "A cute cat" -o minimax-output/cat.png

Output Convention#

All generated files MUST be saved to minimax-output/ under the agent's working directory.

TTS (Text-to-Speech)#

Endpoint: POST /v1/t2a_v2 — returns hex audio, decoded and saved as file.

Models: speech-2.8-hd (recommended, best quality), speech-2.8-turbo (faster), speech-02-hd, speech-02-turbo

python

# Basic TTS
minimax_api.generate_tts("Hello world", output="minimax-output/hello.mp3")

# Chinese with specific voice
minimax_api.generate_tts("红叶最多情，一舞寄相思", voice_id="female-shaonv", output="minimax-output/greeting.mp3")

# With emotion
minimax_api.generate_tts("I'm so happy today!", voice_id="male-qn-qingse", emotion="happy", output="minimax-output/happy.mp3")

Common voice IDs: female-shaonv, male-qn-qingse, male-qn-jingying, presenter_male, presenter_female Emotions: happy, sad, angry, fearful, disgusted, surprised, calm, fluent, whisper (empty = auto)

Music Generation#

Endpoint: POST /v1/music_generation — lyrics required, returns audio URL. Takes 30-300 seconds.

python

# Instrumental (BGM)
minimax_api.generate_music("soft piano, ambient, peaceful", instrumental=True, output="minimax-output/bgm.mp3")

# Song with lyrics
minimax_api.generate_music(
    "indie folk, melancholic",
    lyrics="[verse]\nWalking alone\n[chorus]\nFeeling free",
    output="minimax-output/song.mp3"
)

Image Generation (Text-to-Image)#

Endpoint: POST /v1/image_generation — returns image URLs (immediate).

python

# Basic
minimax_api.generate_image("A cute cat on a windowsill, photorealistic", output="minimax-output/cat.png")

# With aspect ratio
minimax_api.generate_image("Mountain landscape, golden hour", aspect_ratio="16:9", output="minimax-output/landscape.png")

# Multiple images
minimax_api.generate_image("Abstract geometric art, vibrant", count=3, output="minimax-output/art.png")

# With prompt optimizer
minimax_api.generate_image("A man on Venice Beach, 90s documentary", prompt_optimizer=True, output="minimax-output/beach.png")

Aspect ratios: 1:1 (default), 16:9, 4:3, 3:2, 2:3, 3:4, 9:16, 21:9

Image-to-Image Generation#

Endpoint: POST /v1/image_generation with image_file — generate new images from a reference.

python

# From local file
minimax_api.image_to_image("A girl in a library", "minimax-output/face.jpg", output="minimax-output/library.png")

# From URL
minimax_api.image_to_image("Oil painting style", "https://example.com/photo.jpg", output="minimax-output/painting.png")

Video Generation#

Endpoint: POST /v1/video_generation (async) + GET /v1/query/video_generation — polling required.

python

# Text-to-video
minimax_api.generate_video(
    "A golden retriever puppy runs toward camera, tracking shot, golden hour",
    output="minimax-output/puppy.mp4"
)

# Image-to-video (prompt focuses on MOTION only)
minimax_api.generate_video(
    "Petals sway in breeze, soft light shifts",
    mode="i2v", first_frame="minimax-output/flower.png",
    output="minimax-output/flower_video.mp4"
)

# Subject reference (face consistency)
minimax_api.generate_video(
    "A woman walks through a garden, tracking shot",
    mode="ref", subject_image="minimax-output/face.jpg",
    output="minimax-output/garden.mp4"
)

Models: MiniMax-Hailuo-2.3 (default), MiniMax-Hailuo-2.3-Fast (i2v), MiniMax-Hailuo-02 (1080P, 10s) Modes: t2v, i2v, sef (start-end frame), ref (subject reference)

Video Prompt Tips#

Main subject + Scene + Movement + Camera motion + Aesthetic. For i2v: describe motion only, don't repeat what's in the image.

Generate & Send to Feishu#

Use generate_and_send.py to generate content and prepare for Feishu delivery via the feishu-media skill:

bash

# Generate TTS and send
python "{skillDir}/scripts/generate_and_send.py" tts "Hello" --voice female-shaonv --feishu-chat <chat_id>

# Generate image and send
python "{skillDir}/scripts/generate_and_send.py" image "A sunset" --ratio 16:9 --feishu-chat <chat_id>

# Set FEISHU_CHAT_ID env var to avoid passing --feishu-chat every time
export FEISHU_CHAT_ID=oc_xxxxx

After generation, the script outputs file paths and feishu-media send instructions. Use the feishu-media skill to actually deliver the content.

Legacy PowerShell Script#

The original scripts/minimax-api.ps1 is preserved for backward compatibility but is deprecated. Use the Python scripts instead.
