# Overview

***

Welcome to the Validium API reference documentation! This page provides you with a high-level overview of our API capabilities and essential information.

Validium seamlessly integrates with the Ethereum ecosystem. To achieve this integration, we support not only the standard [Ethereum JSON-RPC API](https://ethereum.org/en/developers/docs/apis/json-rpc/) but also introduce L2-specific features that enhance functionality.

To ensure a seamless experience, we impose rate limits on both HTTPS and WebSocket APIs. Generally, these limits are ample, ranging from 10 to 100 requests per second (RPS) per client.
