SLF

Verified Jul 2026

SLF is a small open-source reference dataset of German words grouped by letter and category — cities, countries, rivers, first names, professions, animals, brands, and plants — originally built as sample data for word-guessing and "city, country, river" style games. It's served as a single static JSON file from GitHub Pages, so there's no authentication or rate limit beyond GitHub's own, and no query parameters — every request returns the entire dataset for the client to filter.
