Crypto APIs

Crypto APIs is more than just a collection of endpoints—it's a full-suite Web3 infrastructure provider trusted by over 500 companies globally. Their platform offers access to 14+ modular blockchain services that cover the entire Web3 development stack. From Node as a Service (NaaS) to market data APIs, HD wallet management, transaction simulators, and blockchain event tracking, Crypto APIs empowers developers to create production-ready blockchain applications within days, not months.

With support for major chains like Ethereum, Bitcoin, BNB Chain, Polygon, Solana and more, teams can retrieve full address histories, real-time balances, transaction metadata, and simulate or broadcast transactions—all through unified, REST-based endpoints. Features like transaction fee estimation, block explorers, token contract metadata, and webhook-driven event notifications make the suite ideal for both frontend UX and backend automation.

The platform stands out with its enterprise features such as ISO 27001 certification, encryption in transit and memory, SOC-grade audit trails, and sub-25ms response times. Developers benefit from SDKs in multiple languages including Node.js, Python, Go, PHP, Rust, and more. The included dashboard allows teams to manage API keys, monitor credit usage, set webhooks, and invite team members—all within a scalable, customizable SaaS model.

Competitors like Alchemy, QuickNode, and Infura provide similar services, but Crypto APIs sets itself apart through its deeper integration across blockchain data, automation, market feeds, and developer usability—all accessible with a single API key and industry-leading latency. It’s a future-proof solution for any organization building in Web3.
