Frequently asked questions
How much does Kling 3.0 cost?
Kling 3.0 starts at $0.09 per second of output through the API Stock API. You pay per use from a single prepaid balance — there is no subscription — and the final price scales with parameters such as resolution or duration.
How do I call the Kling 3.0 API?
Send a POST request to https://api.api-stock.com/api/v1/generation/create with your API key and the model id "kling-3.0". The call returns a task id you poll, or a webhook callback when the result is ready. A ready-to-run example is in the quick start above.
What input parameters does Kling 3.0 accept?
Kling 3.0 accepts 6 input parameters, including the required field(s) prompt. Their types, defaults and allowed values are listed in the parameters table above.
What happens if a Kling 3.0 request fails?
API Stock automatically retries the request on a reserve provider. If every provider fails, the charge is refunded to your balance.
Can I use Kling 3.0 with the same API key as other models?
Yes. Every model on API Stock — video, image, music and chat — shares one API key and one prepaid balance, so you can switch to Kling 3.0 without new credentials.
