All JS Rendered requests cost 10 API Credits. However, if you use JS Rendering with premium proxies, it will cost 25 API Credits, and if you use ultra premium proxies with JS Rendering, the cost will be 75 API Credits. We highly recommend that you only use JS rendering if you absolutely need it to extract your target data, as JS rendering will increase your latency and can reduce your success rates which can reduce the volume of requests you can process through the API.
