Overview
ZMOK provides Ethereum JSON-RPC API access and Web3 provider services, allowing developers to interact with the Ethereum blockchain without running their own node. It is compatible with standard Ethereum JSON-RPC methods and can be used as a drop-in replacement for other providers. Signing up gives you an endpoint URL that acts as your access credential.
Beginner Tip
ZMOK uses your personal endpoint URL as authentication, so there is no separate API key header to configure. Simply replace the RPC URL in your Web3.js or ethers.js setup with your ZMOK endpoint to get started.
