What does Crypto APIs do?
Crypto APIs is a blockchain infrastructure suite that gives developers REST API access to data and node services across 30+ blockchain networks. Instead of running your own nodes or scraping blockchain explorers, you get endpoints for transactions, address balances, block data, smart contract metadata, and more. The platform also provides real-time event notifications, AML address screening, and tools to broadcast and simulate transactions. It's essentially a one-stop backend for any project that needs to interact with blockchains without managing the underlying infrastructure.
Under the hood, Crypto APIs breaks its offerings into focused products: Block Data, Blockchain Events, Verify Address (for compliance), Broadcast Transactions, and others. Each product is a set of REST APIs with clear documentation. Developers can choose dedicated nodes (private infrastructure) or shared nodes (Node as a Service) via JSON-RPC. A newer addition is AI Compatibility — 14 MCP servers and an n8n node that lets AI agents like Claude and Cursor query blockchain data directly. The platform also includes Blockchain Fees for estimating transaction costs and a Transaction Simulator for testing EVM transactions.
This tool is built for blockchain developers, crypto exchanges, payment processors, and any fintech company that needs reliable blockchain data. Common use cases include powering multi-currency wallets, real-time transaction monitoring for compliance, building exchange order books, and generating tax reports. If you're building on crypto and don't want to deal with node syncing or data parsing, Crypto APIs provides the data layer out of the box.
