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.
