ZMOK API

Free to Use Varies (check documentation)

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.

Common Errors & Troubleshooting

401 Unauthorized Using an invalid or expired app endpoint URL
Log in to ZMOK dashboard and copy your current endpoint URL; ensure you are using the full URL including your app ID
Method not found Calling an Ethereum RPC method not supported by ZMOK
Check the ZMOK documentation for the list of supported methods; some advanced methods may require a higher-tier plan
