# Overview

As Autheo is built on the Cosmos EVM model, our JSON-RPC API closely mimics that of Ethereum. Developers familiar with Ethereum architecture should find Autheo familiar, and the following API matches those of most EVM compatible Layer-1 blockchains.

This document contains information on the JSON-RPC API endpoints that external applications can use to interact with the Autheo platform.

<Note>
  Examples below use `https://rpc1.autheo.com` (mainnet). For testnet, substitute `https://testnet-rpc1.autheo.com` or `https://testnet-rpc2.autheo.com`. See [Network endpoints](/getting-started/network/endpoints) for the full list.
