# Introduction ## **RPC Fast API Access** The RPC Fast API gives instant access over HTTPS and WebSockets to **Ethereum** and a few selected EVM blockchains, such as **BNB Chain, Arbitrum,** and **Polygon**. We provide a high level of security, stable connection, and an intuitive control panel. * **Standard Interface:** Get access to our JSON-RPC endpoint and 100% healthy nodes on production. * **Stable Connection:** Geo-distributed infrastructure makes it run smoothly without harming the UX. The software updates automatically and saves your time. * **High-level Security:** JSON Web Token application is available for the Enterprise plan. The architecture is error-proofed and consistent. Great for smart contracts. * **Auto-scaling Infrastructure:** AI-based PredictKube mechanism autoscales the node pool to get your project ready for any traffic amount. * **Control Panel:** RPC Fast dashboard is intuitive. Here you will find automatically-built reports about your blockchain hosting state. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
