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.

Duolingo Profile & Streak API
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.

College Majors API
Earnings and employment outcomes for 170+ US college majors, from FiveThirtyEight's analysis of the U.S. Census American Community Survey. For each major: its category (Engineering, Business, Arts…), number of graduates and share who are women, median / 25th- / 75th-percentile earnings of full-time workers, unemployment rate and college-job counts. Look a major up by name or code, list a category, rank majors by earnings or unemployment, or search. Ideal for edtech, career-guidance, student-advising and HR analytics apps.

Flags API
National flag design as an API — built on the classic UCI "Flags" dataset (194 countries) and enriched with each country's ISO 3166-1 alpha-2 code, its Unicode flag emoji and ready-to-use SVG / PNG image URLs. For each flag the API exposes its real design attributes: the number of vertical bars and horizontal stripes, the colours present, the predominant ("main") hue, the colours of the top-left and bottom-right corners, and which symbols appear — circles, crosses, saltires, quartered fields, stars or suns, a crescent, a triangle, an inanimate icon (e.g. an anchor), an animate image (e.g. an eagle) or written text. Look a flag up by country or code, search, or FILTER flags by colour, main hue or symbol — "every flag with a crescent", "flags that are mainly green". Served from memory — always fast.

Constellations API
The 88 modern IAU constellations as an API — the reference an astronomy app, planetarium or education tool needs. For each constellation: its official IAU abbreviation, English name, the Latin genitive used when naming stars (e.g. "Alpha Andromedae"), a size rank, the approximate centre in equatorial coordinates (right ascension / declination) and the constellation name in roughly 25 languages. Look one up by abbreviation or name, search across every language, find which constellation a sky position falls nearest to, or list them all. Distinct from stars-api (individual stars) — this is the reference for the constellations themselves. Served from memory — always fast.
