Native video with sound

Text to video

Describe a scene, movement, lighting, and sound. We send the job securely and return the completed video to your library.

02

Multi-reference

Use several visual references to guide identity, styling, and art direction in a single video request.

03

First and last frame

Define the opening and ending composition, then generate the movement between them.

Prepaid usage

Quick start

From a new account to your first video.

Follow these steps in order. You can create in the dashboard without code, or automate creation from your own server with an API key.

01

Create your account

Register with your email and a strong password. Your dashboard is where you manage balance, jobs, and private downloads.

02

Add credit

Choose Buy credit and complete secure checkout. Your credited balance appears in the dashboard after payment is confirmed.

03

Create in the dashboard

Write a prompt, choose a duration and resolution, then submit. Follow the job status and download the MP4 when it is ready.

04

Or create an API key

Developers can create a private API key in the dashboard. Copy it once, store it in your server environment, and never expose it in browser code.

05

Track and retrieve

Use the task ID returned by the API to check progress. When the task succeeds, download the video through your private account or authenticated API.

Developer access

Use your private API key from your server.

Create or revoke keys in the dashboard. Never place keys in browser code, mobile apps, or public repositories.

Private account

Create, fund, and manage H3 work.

Your dashboard includes your balance, jobs, API keys, and private downloads.
