# 7.1 API Documentation For developers, a robust and well-documented API is the gateway to building powerful applications and services on GRX Chain. Our API documentation provides a comprehensive set of resources to enable seamless integration with the GRX Chain network, allowing for creating dApps, wallets, analytics tools, and more. Our API documentation will include: * EVM-Compatible JSON-RPC API: GRX Chain supports the standard Ethereum JSON-RPC API as an EVM-compatible chain. This is the primary interface for sending transactions, querying block data, and interacting with smart contracts. The documentation will provide a complete list of supported methods, parameters, and return types. * GRXscan Block Explorer API: The GRXscan.io block explorer will offer a dedicated API, allowing developers to programmatically retrieve on-chain data, including transaction history, token balances, and smart contract information for their projects. * Web3 Libraries and SDKs: The documentation will provide detailed guides on connecting to GRX Chain using popular Web3 libraries and SDKs (e.g., Web3.js, Ethers.js), code examples and tutorials for everyday tasks. * Developer Guides and Tutorials: Besides API references, the documentation will feature step-by-step guides for various development tasks, from deploying a simple smart contract to building a full-featured dApp. Our commitment is to provide clear, accessible, and up-to-date API documentation that empowers developers to innovate and build the future of Web3 on GRX Chain. --- # 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.
