- 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 kling/kling-o3, 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 Kuaishou account?
- No. Leap sends your request to Kuaishou's model and gives you what it makes. One Leap account runs Kling O3 and every other model, in the studio, through the API and from your agents.
