MiniMax H3 API
Use MiniMax H3 on Muapi for text-to-video, image-to-video, and reference-to-video workflows. Each workflow uses Muapi's unified asynchronous API pattern, so your application can submit a request, track its status, and retrieve the completed video with one API key.
MiniMax H3 is designed for prompt-led video generation, image animation, and multimodal reference guidance. Choose the workflow that fits your creative pipeline, then use Muapi's standard asynchronous request and polling flow to manage the generation.

Pay per generationWhat is the MiniMax H3 API?
MiniMax H3 is a video-generation model family available through Muapi's unified API. It gives developers three complementary ways to create video: start from a written idea, animate an existing still image, or guide a new video with multimodal references. The same task lifecycle applies to each workflow, so you can build one video-generation pipeline rather than maintaining separate integrations for each mode.
For teams building creative products, marketing tools, video editors, or automated media workflows, MiniMax H3 provides a practical split between open-ended generation and tightly guided shots. Text to Video is the right starting point when the scene exists only in a brief. Image to Video turns approved key art or product photography into motion. Reference to Video combines a prompt with images, clips, and optional audio to preserve the creative direction you already have.
Muapi standardizes authentication, asynchronous task responses, webhooks, and result retrieval across the text-to-video and image-to-video catalog. MiniMax H3 can therefore sit alongside other video models in a routing or evaluation workflow without a new provider account or a second response format.
MiniMax H3 video-generation workflows
Text to Video
Use a descriptive prompt to define the subject, setting, action, camera direction, lighting, pacing, and visual style. This is the flexible mode for concepts, storyboards, and new scenes.
Image to Video
Start with an image that already contains the subject, art direction, and composition you want. Focus the prompt on motion, camera movement, and how the scene evolves.
Reference to Video
Supply images or video clips to guide subject consistency, motion, visual style, and scene continuity. Add optional audio references for richer multimodal direction.
Common MiniMax H3 use cases
Performance marketing
Create product-motion concepts, social ads, and visual variations from campaign briefs or approved product photography.
Pre-production
Turn scripts and storyboards into fast animatics, camera references, and transition studies before a live shoot.
Social content
Generate vertical-ready motion concepts, visual hooks, and short scene cutaways for creator workflows.
Creative tools
Add video generation to a design, presentation, ecommerce, or agent-driven application through one API contract.
How to write better MiniMax H3 prompts
Use a director's brief, not a keyword list
The strongest video prompts establish a clear subject, place, movement, camera choice, and atmosphere. Give motion a reason: a gust of wind moves fabric, a tracking camera follows a runner, or a crane shot reveals the scale of a landscape.
- Subject and action: who or what moves?
- Environment and time: where does the shot take place?
- Camera: dolly, orbit, handheld, locked-off, aerial, or close-up.
- Look: lighting, palette, lens feel, and pacing.
Example prompt
For Image to Video, retain the visual facts already in the image and describe only the intended movement. For Reference to Video, name how each reference should influence the subject, style, motion, or soundtrack.
A macro tracking shot follows a glass perfume bottle on blue silk as morning light moves across the label. The camera makes a slow 180-degree orbit; translucent fabric ripples in a gentle breeze, with soft editorial studio lighting and shallow depth of field.
MiniMax H3 API integration pattern
Every MiniMax H3 request is asynchronous. Submit the generation request and store the returned request ID. Your application can poll for the final media URL or provide a webhook URL when submitting the task. This keeps long-running video work off the request thread and matches the rest of Muapi's generative-media APIs.
- Send a prompt and any supported image inputs to the selected H3 endpoint.
- Receive a request ID immediately and poll it, or supply a webhook for completion.
- Retrieve the completed video from the standard Muapi task response.
Quick start — MiniMax H3 API
Submit a prompt to an H3 endpoint, receive a request ID, and poll the standard prediction result endpoint for the completed video.
1. Submit a generation task
curl -X POST https://api.muapi.ai/api/v1/minimax-h3-text-to-video \
-H "x-api-key: YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"prompt":"A cinematic aerial shot over a misty valley at sunrise","resolution":"2k","duration":5,"aspect_ratio":"16:9"}'
# Response: {"request_id":"REQUEST_ID"}Start with minimax-h3-text-to-video, or use the image and reference endpoints for guided workflows.
2. Retrieve the completed result
curl https://api.muapi.ai/api/v1/predictions/REQUEST_ID/result \ -H "x-api-key: YOUR_API_KEY" # The completed response contains the generated video URL.
The response contains the task status and generated output URL when the video is complete.
MiniMax H3 API FAQ
What can I create with MiniMax H3?
Create videos from a text prompt, animate a source image, or guide a new video with image, video, and optional audio references.
Which MiniMax H3 workflow should I use?
Use Text to Video for an original scene, Image to Video when you need to animate a supplied composition, and Reference to Video when multiple assets should guide the output.
How do I keep my application responsive during generation?
Store the request ID returned by the submit call. Poll the prediction result endpoint from a worker or receive completion through a webhook instead of keeping a browser request open.
Can I use MiniMax H3 with other video models?
Yes. Muapi uses a shared authentication and task-response pattern across the catalog, making it practical to route, compare, or fall back between video models in one product.
How is MiniMax H3 billed?
MiniMax H3 uses Muapi's pay-per-generation billing model. Review the model page for the current pricing details associated with the selected workflow.
Will I need a separate API key?
No. MiniMax H3 uses your existing Muapi API key, together with the same task polling and webhook pattern as other Muapi models.
