Wikipedia API
A fast, clean wrapper over the official Wikimedia APIs covering every Wikipedia language: full-text article search with snippets, lead-section summaries (extract, short description, thumbnail and canonical URL), "on this day" historical events, births, deaths and holidays for any calendar day, and a random-article endpoint. Every endpoint takes a "lang" parameter (en, de, fr, es, simple, zh and any other Wikipedia language) and accepts input via the query string or the request body. Returns lean, predictable JSON with HTML stripped and entities decoded — no scraping, no rate-limit juggling, no client-side parsing. Ideal for chatbots and RAG pipelines, trivia and "this day in history" apps, knowledge panels, education and research tools.

Stopwords API
Stopword lists and removal for 58 languages. Fetch the full stopword list for a language, see all supported languages with their word counts, check whether a single word is a stopword, or strip stopwords out of a block of text to get a clean keyword stream. Built on the open stopwords-iso dataset and served entirely in-memory, so responses are instant and the service is always available. Ideal for search indexing and relevance, NLP preprocessing and text mining, keyword extraction, tag generation and content tooling.
