# APIs overview

> Autheo Chain exposes two public API interfaces: an Ethereum-compatible JSON-RPC API and a block explorer REST API.

Autheo Chain exposes two public API interfaces for interacting with the network programmatically.

| API      | Best for                                                                                                                                                                                    | Docs                                         |
| -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------- |
| JSON-RPC | EVM interactions — deploying contracts, sending transactions, querying balances, subscribing to events. Compatible with ethers.js, viem, web3.js, and any standard Ethereum client library. | [JSON-RPC overview](/apis/json-rpc/overview) |
| REST     | Read-only data access — blocks, transactions, addresses, token balances. Simple HTTP requests, no library required.                                                                         | [REST overview](/apis/rest/overview)         |
