This repository provides a REST API for retrieving random words with optional filtering by language, length, count, and difficulty (based on Wikipedia word frequency). The application is built with Scala using the Cask web framework, loads word lists from JSON files at startup, and uses Redis for IP-based rate limiting. Key features include difficulty filtering via parallel Wikipedia API calls with caching and fallback mechanisms, efficient random word selection algorithms, and multi-language support through community-contributed JSON files. The architecture is monolithic with clear separation of concerns across service objects for language handling, word selection, rate limiting, and external API integration.
