Setting Up Your First API: A Step‑By‑Step Introduction to REST and JSON‑RPC Endpoints

APIs are the gateways to data and services—knowing how to call your first endpoint is essential for any developer. In Setting Up Your First API, Steven Paul provides a hands‑on tutorial for connecting to REST and JSON‑RPC interfaces, covering:

• Understanding HTTP methods (GET, POST, PUT, DELETE) and status codes.
• Authenticating requests with API keys and tokens.
• Parsing JSON responses and error handling.
• Writing your first script to fetch data from a public blockchain node.

This workbook includes annotated code examples, troubleshooting tips, and exercises designed for software engineers, technical students, and blockchain developers to build confidence calling APIs in any environment.
