- H3 Max Turbo Extend: Continues your video by 5, 10 or 15 seconds from a prompt that says what happens next, and returns the whole video with its new ending.

- Can I use what I make commercially?
- Yes. You own what you make on Leap, so you can use it commercially, and we never train AI on it. The people and brands shown in a result can still have rights in it; the Terms say more.
- Is there an API?
- Yes. Leap's REST API runs it as fal/h3-max-turbo-extend, at the same price per run as the studio, and agents can call it through Leap's MCP server. The request is at the bottom of this page.
- Do I need a fal account?
- No. Leap sends your request to fal's model and gives you what it makes. One Leap account runs H3 Max Turbo Extend and every other model, in the studio, through the API and from your agents.

The request
The same envelope for every model; only the model and its input change. With prefer: wait=60 the answer holds the result when the run finishes within a minute; a longer one is read again by its ID. A file input takes the ID that POST /v1/files returns for your upload. Agents can call it through the MCP server at app.tryleap.ai/api/mcp.
