About SLF

SLF provides a JSON API endpoint at slftool.github.io/data.json that returns word-game data organized by starting letter, with categories including city, country, river, name, profession, animal, and brand. The response structure groups terms under each letter, formatted as arrays of category values.

The tool is aimed at developers building word or trivia games, particularly those based on categorizing words by initial letter across common categories like geography, names, and professions.
