What it makes
Made with Veo 3.1 Lite
Real Veo 3.1 Lite runs on Leap. Each one passed Leap's media quality check before it was shown.

“The colossal jellyfish pulses and drifts slowly across the dusk sky above the desert town, its glowing tendrils sway and trail over the rooftops, the tiny people on the street look up, the camera tilts up slowly. Dreamlike, cinematic.”

“Smooth cinematic drone approach: the camera glides forward and slowly descends toward the circular timber-and-glass library in the misty pine forest, morning fog drifts between the trees, tiny people walk along the rooftop garden ring, warm windows glow, sunrise light. Stable aerial shot.”

“Science fiction: a slow cinematic dolly forward through the quiet white observation deck toward the crew member standing at the panoramic window, the giant ringed planet drifts slowly outside, soft light shifts across the floor. Smooth, majestic.”

“Abstract motion design: the liquid chrome ribbon slowly folds, ripples and twists through the dark room while the camera orbits gently around it, crisp mirror reflections of the strip lights slide across its surface, small caustic sparks on the floor. Smooth, premium, seamless motion.”

“Interior film: the sheer linen curtains billow gently in a soft breeze, sunlight and window shadows shift slowly across the oak floor, mist drifts among the pines outside, the camera dollies slowly sideways through the living room. Calm, architectural, no people.”

“Steam rises gently from the spaghetti, warm sunlight drifts across the wooden table, slow push-in”
Inputs
What Veo 3.1 Lite takes
Only prompt is needed; everything else has a default. The same schema is public, with no key, at api.tryleap.ai/v1/public/models/google/veo-3.1-lite.
MCP
Or let your agent call it.
Leap's MCP server lets Claude Code, Claude, VS Code and other MCP clients run Veo 3.1 Lite, read its inputs and fetch the result, on your balance. Signing in happens in the browser, so there is no key to paste.
claude mcp add --transport http leap https://app.tryleap.ai/api/mcpClaude Code signs you in through the browser the first time it calls Leap.

Questions
Veo 3.1 Lite API questions
- How much does the Veo 3.1 Lite API cost?
- A 4-second 720p clip with sound costs $0.272. By length, resolution and sound, a call costs $0.164 to $0.88. That is the provider's list price plus our margin, the same as in the studio. POST /v1/quotes prices any input for free before you run it.
- Can I try the Veo 3.1 Lite API for free?
- No. API keys run on paid credit, so a key's first call needs a top-up, and quotes are free. A 4-second 720p clip with sound costs $0.272. A first top-up of $5, with no fee, covers 18 default calls.
- Do I pay for calls that fail?
- No. The price is held when a call starts and charged only if it succeeds. A call that fails, or that the model's safety filter refuses, comes back with status "failed" and a failure_cause, and the hold is released.
- Is this Google's own API?
- No. Leap is a separate service: it sends your call to Google's model and gives you what it makes, so you need no Google account. One Leap key runs Veo 3.1 Lite and every other model in the catalog, from one balance.
- What are the rate limits?
- 600 requests a minute per API key and 300 a minute per IP address. A batch starts up to 50 calls in one request. A 429 says how long to wait in its Retry-After header.
- Can an AI agent call it?
- Yes. Leap's MCP server lets Claude Code, Claude, VS Code and other MCP clients find Veo 3.1 Lite, read its inputs, run it and fetch the result on your balance. The client signs you in through the browser, so there is no key to paste.
