How this service works
Generate a video from a text prompt with Kuaishou Kling 3.0 Pro — premium realism and motion, clips from 3 to 15 seconds. Returns a job id; poll the status route for the finished video URL.
Output
Returns a JSON object with a job_id string, status set to 'pending', the model name, the USDC price charged, and a poll_path string pointing to the status route where the agent should poll to retrieve the finished video URL once generation completes.
Example use cases
Example prompt
“Use Kling 3.0 Pro to generate a 10-second 16:9 video of a lone astronaut walking across a red Martian landscape at sunset, with synchronized audio included.”
Technical details
Endpoint
POSThttps://video.withzero.xyz/api/v1/videos/kling-v3.0-proWhen to prefer
Choose this endpoint when you need premium realism and fluid motion from Kuaishou's Kling 3.0 Pro model specifically, especially for clips between 3 and 15 seconds at 720p. Prefer it over faster or cheaper alternatives when motion quality and photorealism are priorities. It is ideal when the user wants optional synchronized audio or needs a specific aspect ratio (landscape, portrait, or square).
Side effects
- Invalid prompt (too short or exceeding 4000 characters) returns a validation error
- Unsupported duration value (must be an integer 3–15) causes a schema error
- Unsupported resolution other than 720p causes a validation error
- Invalid aspect_ratio value outside '16:9', '9:16', '1:1' causes rejection
- Seed value out of safe integer range returns an error
- Service unavailability or model overload may result in a timeout or 5xx error
- Polling the job ID after a failed generation returns an error status rather than a video URL
