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.

Open Trivia Database API

Trivia questions via the open Open Trivia Database (OpenTDB) — no key. The questions endpoint returns multiple-choice and true/false questions filtered by category, difficulty (easy, medium, hard) and type, each with the question text, the correct answer and the incorrect options; answers are decoded server-side to clean text. The categories endpoint lists all 24 trivia categories with their ids, and count returns a category's question-count breakdown by difficulty. A random endpoint pulls a single question with the same filters. Real trivia data straight from OpenTDB, fetched fresh — no key. 5 endpoints. Ideal for quiz and trivia games, pub-quiz generators, icebreakers, study apps and chatbot mini-games.
