- A 5-second clip without sound costs $0.462 at the default settings. By length and sound, a run costs $0.2772 to $1.848. You see the exact price before you press go, and a run that fails costs nothing.
- Is Kling O3 Reference free to try?
- Yes. Sign up with a Gmail, Outlook or work address and you start with $2 of free credit, no card needed. The cheapest run is $0.2772 (a 3-second clip without sound), so the credit covers seven of those. After that you pay per run, in dollars, with no subscription.
- 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-reference, 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 Reference 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.
