An API Endpoint, often referred to as an RPC Node in blockchain, is a network interface that enables external applications to interact with a blockchain network. It allows developers to query blockchain data (e.g., balances, transaction status) and send signed transactions via protocols like JSON-RPC. These endpoints are essential for dApps, wallets, explorers, and bots, providing access to execution and consensus layer data. Services like Infura, Alchemy, and QuickNode provide scalable API access to Ethereum and other chains, enabling decentralized applications without requiring users to run their own node.
