#learning

Live public profile and language-learning stats from Duolingo, the world's largest language-learning platform — no key, nothing stored. This is the gamified-learning social view: a learner's XP, daily streak, courses and progress, distinct from every other social platform in the catalogue. The user endpoint returns a profile summary — display name, bio, location, join date, total XP, the current daily streak, the language being learned and the from-language, the current course, Super/Plus status and a course count. The courses endpoint returns the per-language breakdown: every course the learner studies with its title, learning and from languages, XP earned and crown count. The streak endpoint returns the streak detail — the current streak length and, when the learner makes it public, the streak start date and longest streak. Lookup is by username; the official mascot account "duo" is always available. Build streak widgets, learning-accountability bots, language-club leaderboards and profile cards on top of real Duolingo data. Private or non-existent usernames return a clean 404.

Wikibooks as an API — the Wikimedia library of free, open-content textbooks, manuals and learning guides, community-written and freely licensed. Wikibooks covers programming and computer science, mathematics, the natural and social sciences, languages, engineering, cooking, music and much more, organised as books made up of chapters. This API wraps the official Wikibooks MediaWiki service into clean JSON. /v1/search?q=python programming searches the library and returns matching book and chapter titles with a text snippet and word count. /v1/book?title=Python Programming returns a book's overview — its short description, the plain-text introduction, a cover thumbnail and the canonical URL. /v1/chapters?title=Python Programming lists the book's chapters (its subpages, e.g. Python Programming/Operators, Python Programming/Classes), each with the chapter name and URL, so you can browse and present a whole book's structure. Titles are Wikibooks page names; get the exact title from /v1/search first. Ideal for e-learning platforms and study apps, open-education and OER tools, reading lists, and developer/teaching content aggregators. Content is licensed CC BY-SA by the Wikibooks community. Distinct from book-metadata catalogues — this is actual free educational content. For travel guides see the Wikivoyage API, for the encyclopaedia the Wikipedia API.
