ONE VIDEO RESOURCE

A predictable asynchronous API workflow

Every accepted request returns a Video ID, quote snapshot, and queue state. Poll the same resource until it succeeds, fails, or is cancelled.

Create

Submit the model, tier, prompt, duration, resolution, aspect ratio, and optional image inputs with an Idempotency-Key.

Poll

Read queued, running, progress, queue position, and terminal state without holding one long HTTP request open.

Store

On success, copy the result from its signed download URL before the returned expiration time.

SUPPORTED WORKFLOWS

Text, frames, and ordered reference images

The public contract validates input combinations before routing them to a published execution profile.

Workflow	Request input	Best for
Text-to-video	Prompt without images	Scenes, motion, camera, and audio described in text
First/last-frame video	`frame_images`	Controlling an opening frame and optional ending frame
Reference-image video	`reference_images`	Preserving subject, product, scene, or style guidance

MINIMAX H3 API FAQ

Questions developers ask before integrating

How much does the MiniMax H3 API cost?

vgenv Fast 768p generation costs $0.003 per output second: $0.003 for one second, $0.015 for five seconds, and $0.045 for fifteen seconds. Standard 768p is $0.0045 per second and Quality 768p is $0.012 per second. The accepted Video response contains the final quote snapshot.

Is this the official MiniMax API?

No. vgenv is an independent API service. vgenv keys, endpoints, billing, model identifiers, and response fields are separate from MiniMax's first-party platform.

Does the API support image-to-video?

Yes. Use frame_images for first and optional last frames, or reference_images for up to nine ordered reference images. The two input patterns cannot be combined in one request.

Do failed generations cost money?

The quote is reserved when a job is accepted and settled only after success. Platform failures and queued cancellations release the reserved Project balance.

Do I need a Node.js or Python SDK?

No. The API uses standard Bearer authentication, HTTP, and JSON. Runnable curl, Node.js, and Python examples are available on GitHub.
