The classical-music repertoire as an API — powered by Open Opus, an open catalogue of classical composers and their works. Search composers by name or browse them by musical epoch (Medieval, Renaissance, Baroque, Classical, Romantic and beyond), getting each composer's full name, epoch and birth/death years; then list a composer's works, optionally filtered by genre — orchestral, chamber, keyboard, stage, vocal or opera. From Bach and Mozart to Beethoven's 44 orchestral works, it turns the canon of classical music into a clean search-and-browse API. A classical-music repertoire reference — distinct from commercial music catalogues of tracks, artists and albums. Ideal for classical-music, education, concert-programming, streaming and media applications. Open data from Open Opus (CC-BY-SA / CC0).

The Jewish calendar as an API — powered by Hebcal. Convert any date between the Gregorian and Hebrew calendars (with the formatted Hebrew date and the Jewish events falling on that day), list the Jewish holidays of any year — major and minor festivals, Rosh Chodesh and special Shabbatot — each with its English and Hebrew name, date and category, and get this week's Shabbat candle-lighting time, Torah portion (parashah) and Havdalah time for any location by GeoNames id or coordinates. From Rosh Hashanah and Yom Kippur to Passover, Shavuot and Hanukkah, with Hebrew dates rendered in Hebrew script, it is ideal for calendar, scheduling, event, religious and cultural applications. A Jewish-calendar resource — distinct from secular public-holiday and Islamic prayer-time APIs. Open data from Hebcal (CC-BY 4.0 / GPL).

Every UNESCO World Heritage Site as an API — all 1,236 inscribed sites worldwide (cultural, natural and mixed) from the official UNESCO World Heritage List. Look up any site by its WHC id (e.g. Galápagos Islands, Machu Picchu, Historic Centre of Rome) with its country, exact coordinates, the year it was inscribed and the UNESCO selection criteria. Search and filter by name, country, category (cultural / natural / mixed) and inscription year, or find every World Heritage Site near any coordinate by great-circle distance. Ideal for travel, tourism, maps, education and cultural-discovery apps.
