Level 0111 (7) - API Development

At the crossroads of the Digital Realm stand the great API Gateways—magical interfaces that allow disparate systems to communicate in harmony. Here, adventurers learn the ancient protocols of REST, master the arcane arts of authentication, and forge the secure bridges that connect the modern digital world.

🎯 Level Overview

Theme: Backend Development

XP Range: 700-900

Tier: Journeyman ⚔️

API development represents the culmination of the Journeyman tier, bringing together skills from previous levels into the practical craft of building web services. This level teaches you to create APIs that are not just functional, but elegant, secure, and well-documented.

From understanding RESTful principles to implementing OAuth authentication, from designing proper error responses to managing API versioning—you’ll gain the complete skillset needed to build production-grade APIs that power mobile apps, web frontends, and third-party integrations.
