MiniMax H3 Video API Is Live on APIMaster.ai — Get 60% Off

What is MiniMax H3?

MiniMax H3 is MiniMax’s general-purpose multimodal generation model for video and related creative workflows. The official launch article describes a model that can understand unified context across text, images, video and audio, generate video with native stereo sound, and produce clips up to 15 seconds at 2K resolution.

Unlike a text-only video prompt tool, H3 is designed to understand relationships between sources. A creator can describe a camera movement from a reference video, a character from an image, and a vocal or sound direction from audio in natural language. This makes the model relevant to workflows where the desired result depends on more than one modality.

MiniMax H3 features and advantages

Multimodal context understanding

H3 is built to combine text, images, video and audio as one creative context. This is useful for reference-driven generation, product demonstrations, visual storytelling and content variations where the prompt needs to describe how several inputs relate to the output.

Native stereo sound

MiniMax says H3 jointly models video and audio, with native stereo audio output. For a short campaign clip, product teaser or film concept, this can reduce the need to create a silent video first and add a separate sound layer later. Always review generated audio before publishing, especially for brand and commercial use.

2K output and detail recovery

H3 supports 768P and 2K output. MiniMax describes its in-context regeneration approach for 2K as a way to reuse the original multimodal context when recovering visual detail, including small text and fine elements. 2K costs more per second, but is a better fit when the output will be cropped, displayed on a product page or used in an advertising workflow.

Instruction following and controllable creative work

The official announcement highlights instruction following, accurate text and brand rendering, native multi-shot modeling, generalized reference and editing, and video-to-video motion transfer. These capabilities make H3 interesting for:

• advertising and e-commerce product videos;
• animated posters and product websites;
• film opening titles and storyboards;
• image-to-video and motion-reference experiments;
• multilingual creative variations for global campaigns.

Capabilities depend on the request format and upstream implementation. Test a representative prompt before committing a production workflow.

MiniMax H3 pricing on APIMaster.ai: up to 60% off

APIMaster’s current launch offer discounts eligible MiniMax H3 routes by up to 60% compared with the official reference prices. The public marketplace currently uses per-second pricing:

• 768P: $0.032/second at the discounted APIMaster price;
• 2K: $0.052/second at the discounted APIMaster price.

For example, a four-second 768P clip is approximately $0.032 × 4 = $0.128 before any account-level group or promotion rules. A four-second 2K clip is approximately $0.052 × 4 = $0.208. APIMaster charges according to the output duration reported by the asynchronous task when that usage is available.

The marketplace is the source of truth for the current offer. Discounts, channel capacity, availability and upstream pricing can change; check the live MiniMax H3 card before adding balance or sending high-volume traffic.

How to use MiniMax H3 through APIMaster

1. Create an APIMaster account.
2. Open the model marketplace and select MiniMax-H3.
3. Add balance and create an API key in the console.
4. Send a request to the video generation endpoint:

curl -s "https://apimaster.ai/v1/video/generations" \
  -H "Authorization: Bearer YOUR_APIMASTER_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "MiniMax-H3",
    "prompt": "A red paper boat crossing a calm lake at sunrise, cinematic camera movement",
    "duration": 4,
    "size": "768P",
    "ratio": "16:9"
  }'

The API returns a task ID immediately. Poll the task until it is completed, then download the video content. The request supports duration from 4 to 15 seconds and size values of 768P or 2K.

Why use APIMaster for MiniMax H3?

MiniMax H3 provides the generation capability; APIMaster adds the API operations layer around it:

1. One OpenAI-compatible integration — use a familiar base URL and bearer-token pattern instead of building a separate billing integration for each provider.
2. Live route and price comparison — see available channels, model pricing and current discount information in one marketplace.
3. Model and channel verification — use APIMaster’s AI model tester to check whether a route behaves like the advertised model before scaling traffic.
4. Per-second media billing — video duration and resolution are represented in the task billing context, making the expected cost easier to audit.
5. Usage logs with request details and video preview — review the prompt, duration, resolution, task status and generated video from the console.
6. One wallet for multiple AI providers — switch between video, image, speech and language models without maintaining separate gateway integrations.

This combination is useful for teams prototyping creative applications, agencies producing multiple versions of an ad, and developers who want to compare model quality and route reliability before choosing a long-term upstream setup.

FAQ

What is the MiniMax H3 API model name? Use MiniMax-H3 in the video generation request. The APIMaster marketplace card is the authoritative source for the currently available route identifier.

Does MiniMax H3 support 2K video? Yes. The launch supports 2K output, with a maximum duration of 15 seconds. APIMaster exposes both 768P and 2K options.

How much does MiniMax H3 cost on APIMaster? The current launch offer is up to 60% off. The listed discounted reference prices are $0.032/second for 768P and $0.052/second for 2K; confirm the live marketplace card before use.

Does H3 generate sound? MiniMax describes native stereo sound and jointly modeled audio-video generation. Output quality and exact behavior can vary by prompt and route, so review results before publication.

Can I use one APIMaster key for other models? Yes. APIMaster provides a unified account and compatible API access across supported model families; change the model and endpoint according to the relevant documentation.

How do I check the real model behind a route? Run a representative request through the APIMaster model tester, then compare response behavior, latency and usage logs before production deployment.
