Frequently asked questions
What is Kling?
Kling is the state of the art video generation AI model developed by Kuaishou, which is one of the world's largest video-based social network with a user base over 400 million users. This model allows users to create high quality, realistic videos from user-input text prompts, static images, or existing videos. The generated videos can be extended up to minutes in length, are physically accurate, and allows for various aspect ratios.
What is the Kling API?
Since Kuaishou currently does not offer API for their Kling model, therefore PiAPI took on initiative and created the unofficial Kling API for developers worldwide, allowing you to integrate text-to-video, image-to-video, and video-to-video capabilities into your application or platform!
What type of videos can I make with Kling API?
Our Kling API can help users generate cinematic videos all types. Our API also enables the creation of video extensions from original videos. Each extension introduces an additional 4.5 seconds of content, precisely controlled by user text prompts!
What are the current limitations with regarding to the Kling Model?
Sometimes the generated resolution is not as high as users would hope for (i.e. 1080p), but with time and as inference infrastructure become more robust from Kuaishou, it will most likely solved with more computing power.
Can I use videos generated from the Kling API for commercial purposes?
We'd recommend waiting for more information from Kuaishou regarding this issue. Currently all videos generated will have the Kling watermark, and some users might try to remove the watermark with third-party tools. However, to avoid potential copyright issues, it would be more prudent to adhere to existing and future copyright terms from Kuaishou.
Are there refunds?
No, we do not offer refunds. But when you first sign up for an account on PiAPI‘s Workspace, you will be given free credits to try our Kling API (specifically the "Pay-as-you-go" service) before making payments!
