kling 4.0 Product Information

What is kling 4.0?

reAPI is an AI API aggregator that provides a unified endpoint and a single API key for accessing models across video, image, language, audio, and other AI categories. It offers pay-as-you-go billing, automatic routing and failover, and says it does not store request bodies or model outputs. The site also documents models such as Kling 4.0; Kling 4.0 is marked as coming soon, while Kling 3.0 is available now.

How to use kling 4.0?

Create an account and an API key in the dashboard, add credits, then call the unified API endpoint with the desired model name. Use the model documentation for request parameters and pricing. For Kling 4.0 specifically, the page says it is not yet available through an API; users can build with Kling 3.0 and switch model IDs when Kling 4.0 becomes available.
