Ethereum API Postman collection

Here you will have access to a Postman collection to test the Ethereum API methods using your Ethereum Chainstack endpoint.

What is Postman?

Postman is a popular collaboration platform for developers that simplifies the process of building, testing, and documenting APIs. It allows developers to send HTTP requests and receive responses in a user-friendly interface, making it easy to debug and test APIs.

This collection allows you to test Ethereum RPC methods using your Chainstack node conveniently.
